Available in PDF, EPUB and Kindle. Book excerpt: Graphene-based materials have been the focus of intense research in recent years, and owing to the desirable properties they possess, the variety of potential applications for them is likewise impressive. Chapter 1 discusses graphene nanoribbons (GNRs) and how their precise atomic features exhibit critical influence over electronic characteristics such as band gaps, magnetic edge states, and topological phases. One can therefore engage in design of molecular precursors to build atomically precise GNRs from the bottom up with desired features which can be probed with surface science techniques. These elements include ribbon width, edge geometry, heteroatomic doping, and many more. In this dissertation are results of scanning probe microscopy experiments to examine structural and electronic characteristics of several GNR structures derived from surface-assisted synthesis techniques.First, we studied the growth of chevron GNRs on Cu(111) (Chapter 2). Epitaxial growth of chevron polymers and GNRs at low temperatures arose out of the strong interactions between structure and surface.In Chapter 3 we discuss the development of an alternative deposition technique, direct contact transfer (DCT). It arose as an analogue of dry contact transfer for solution-synthesized GNRs. The procedure was demonstrated for two precursors, and the intermediates observed in the process of annealing were determined by DFT to be stabilized by Ï0-Ï0 interactions.Chapter 4 covers the on-surface synthesis of laterally extended chevron GNRs (eGNRs). By slight modification of the chevron precursor structure, the band gap of the GNRs was reduced in accordance with established theory. In Chapter 5 results are presented on the on-surface synthesis of intrinsically porous chevron-derived GNRs. These GNRs featured electronic states at their pores as well as reduced band gaps relative to chevron GNRs.Chapter 6 details work on the growth of GNRs from a precursor with two centers of rotation and the potential for influencing its self-assembly.Finally, Chapter 7 contains a summary of the work performed as well as directions to be explored in the future as relate to this project.

Available in PDF, EPUB and Kindle. Book excerpt: On-surface synthesis is appearing as an extremely promising strategy to create organic nanoarchitectures with atomic precision. Molecular building blocks holding adequate functional groups are dosed onto surfaces that support or even drive their covalent linkage. The surface confinement and the frequent lack of solvents (most commonly being performed under vacuum conditions) create a completely new scenario fully complementary to conventional chemistry. In a pedagogical way and based on the most recent developments, this volume presents our current understanding in the field, addressing fundamental reaction mechanisms, synthetic strategies to influence the reactions according to our needs, as well as the ultimate growth and characterization of functional materials. Verging on chemistry, physics and materials science, the book is aimed at students and researchers interested in nanochemistry, surface science, supramolecular materials and molecular devices.

This book was released on 2006 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphene nanoribbons (GNRs) have recently attracted great interest because of their novel electronic and magnetic properties, as well as their significant potential for device applications. Although several top-down techniques exist for fabricating GNRs, only bottom-up synthesis of GNRs from molecular precursors yields nanoribbons with atomic-scale structural control. Furthermore, precise incorporation of dopant species into GNRs, which is possible with bottom-up synthesis, is a potentially powerful way to control the electronic structure of GNRs. However, it is not well understood how these dopants affect the electronic structure of GNRs. Are these effects dependent on the dopant site? Can the band gap be tuned by doping? This dissertation helps to answer these questions through studying the electronic structure of bottom-up grown GNRs with controlled atomic dopants. The effects of edge and interior doping with different atomic species such as sulfur, boron and ketone were investigated and showed significant site dependence. Topographic and local electronic structure characterization was performed via scanning tunneling microscopy & spectroscopy (STM & STS) and compared to first-principle calculations. The chemical structure of GNRs and GNR heterojunctions was characterized by CO-tip-functionalized non-contact atomic force microscopy (nc-AFM) as well as by a newly developed technique of bond-resolved STM (BRSTM). In an effort to develop a new method for directly synthesizing GNRs on an insulating substrate, we also studied light-induced photo-isomerization of azobenzene molecules adsorbed on an insulating surface of CVD-grown monolayer boron nitride (BN) on Cu(111). This study provides important insights into molecular behavior on an insulating surface, how to couple light to an STM system, and how to utilize local field enhancement effects due to surface plasmon resonance.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in bottom-up synthesis of atomically precise graphene nanoribbons (GNRs) are paving the way for new technologies with angstrom-scale features that host a myriad of electronic, spin, and topological properties. Studying the ultrafast phenomena relevant to the optoelectronic potential of these GNRs requires extreme spatio-temporal resolution. Conventional techniques for atomic-scale investigation of materials, such as scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS), lack the necessary time resolution to investigate ultrafast dynamics. Meanwhile, conventional ultrafast measurements are able to time-resolve the optical excitations of these GNRs, but, they lack the requisite spatial resolution to perform more precise experiments on isolated individual structures. Instead, they act on ensembles and average over many GNR lengths, orientations, and sample qualities.With the development of terahertz scanning tunneling microscopy (THz-STM), coherent control of tunneling electrons on sub-picosecond timescales is now possible in an STM tunnel junction. However, to fully empower THz-STM as a scientific tool for materials science, an approach to characterize the electronic properties of new materials and nanostructures without prior knowledge of the sample response is needed. This demands the establishment of terahertz scanning tunneling spectroscopy (THz-STS) with atomic spatial resolution and an approach to analyzing such measurements.In this thesis, we demonstrate atomic-scale THz-STS for the first time by extracting the differential conductance (dI/dV) from a model GNR system with angstrom-scale resolution in all three spatial dimensions. We utilize bottom-up synthesis to construct atomically precise 7-atom-wide armchair graphene nanoribbons (7-AGNR) on an Au(111) substrate. THz-STM is applied to probe the electronic structure of a 7-AGNR while operating at ultralow tip heights, where the distance between STM tip and GNR is reduced by ~3.0-4.0 A. compared to conventional STM tip heights. We construct a model of the GNR electronic density of states and apply THz-STS to a collection of THz-STM images taken at different incident THz field strengths to construct dI/dV maps of the frontier orbitals on a 7-AGNR segment. Lastly, a set of time-domain measurements are performed in the hopes of observing dynamical effects associated with charging of the GNR during charge injection by the THz-STM. The aforementioned steady-state THz-STS results are sufficient to describe the time-domain measurements without charging, suggesting further sample preparation is needed to decouple the GNR from the Au(111) surface and reveal transient effects.We further develop and test an algorithm, based on a polynomial representation of the junction I-V curve, for extracting the tunnel junction dI/dV accessed by an ultrafast THz-STM probe in both steady-state and optical-pump/THz-STS-probe experiments. We test our algorithm against a set of model systems constructed to represent typical STM samples, e.g., metals, semiconductors, and molecules. Then, we simulate a THz-STS experiment wherein we address systematic error by defining a procedure to determine the algorithm parameters. After setting the stage with steady-state THz-STS, our algorithm is expanded upon, and we show how a dynamic junction I(V) predicted for an optical-pump/THz-STM-probe experiment can be extracted from THz-STS measurements. By applying the cross-correlation theorem in the frequency domain we find that the time-resolution of THz-STS is not limited to the input bandwidth of the ultrafast THz voltage pulse. As a result, our pump-probe THz-STS algorithm reveals dynamics faster than a single oscillation cycle of the THz transient,and in the future may be combined with atomically resolved THz-STS experiments to bridge a new frontier of ultrafast materials science.

Available in PDF, EPUB and Kindle. Book excerpt: Recently, there has been a considerable upsurge of interest in heavily doped semiconductors. This interest is due primarily to the expanding range of applications of such. materials. Moreover, the heavy doping of semiconductors produces new effects (the forma tion of impurity aggregates, the appearance of allowed states in the forbidden band, etc J, which are of great interest in solid-state physics. The rapid growth in the number of papers on heavily doped semiconductors makes it difficult to review the results obtained so far. Therefore, many investigations carried out in 1966-7, par ticularly those on AIIIBV semiconductors, are not discussed in the present monograph, which represents the state of the knowledge in 1965. Nevertheless, the author hopes that, in spite of this, the book will be useful. An attempt is made, first, to review investigations of heavily doped semiconductors from a certain viewpoint and, sec ondly, to suggest some ideas (Chap. 5) which may be controversial but which are intended to stimulate further studies of heavily doped semiconductors which can be regarded as a special case of dis ordered systems. The work of American scientists investigating heavily doped semiconductors, in particular the efforts of E. O. Kane, J. 1. Pan kove, R. N. Hall, R. A. Logan, W. G. Spitzer, F. A. Trumbore, and many others, is well known to Soviet investigators. It gives me pleasure to learn that Western readers will now have an - v vi PREFACE portunity to become acquainted with the work done in the USSR.

Available in PDF, EPUB and Kindle. Book excerpt: Bottom-up approaches allow the production of ultranarrow and atomically precise graphene nanoribbons (GNRs) with electronic and optical properties controlled by the specific atomic structure. Combining Raman spectroscopy and ab initio simulations, we show that GNR width, edge geometry, and functional groups all influence their Raman spectra. As a result, the low-energy spectral region below 1000 cm-1 is particularly sensitive to edge morphology and functionalization, while the D peak dispersion can be used to uniquely fingerprint the presence of GNRs and differentiates them from other sp2 carbon nanostructures.
