Book excerpt: The focus of this project is the characterization of two types of interfaces of technological importance: SiO2/Si interfaces relevant to ultra thin gate oxides used for next-generation semiconductor electronics, and bimetallic interfaces (ultra thin films of metals on other metals) that have potential catalytic applications. The main tool is high resolution soft x-ray photoemission spectroscopy (SXPS) using synchrotron radiation at the National Synchrotron Light Source (NSLS). Device-grade films of silicon dioxide and silicon nitride have been grown on Si substrates and new insights into the control of interface electronic state density are found. In addition, SXPS has provided new results on the stability of transition metal films on tungsten substrates: monolayers of Pt, Pd, Ir, Rh are thermally stable, but multilayer films of the same metals form surface alloys.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of the group from NCSU-Rutgers (Jack Rowe's group, in collaboration with Ted Madey) is to use core level photoemission to study inerfaces and surfaces of electronic materials and metallic systems. There is also an effort to upgrade this beamline to a Spherical Grating Monochromator (SGM) which is being performed in collaboration with Steve Hulbert of NSLS. Since gate oxides used in current devices have continued to decrease in thickness with corresponding improvements in oxide growth, processing and device properties, we have reinvestigated the issue of the interface of SiO2/Si(111) using the current state-of-the-art methods of gate oxide growth. The Si(2p) core level has a relatively large chemical shift which is nearly ideal for identifying the interface oxide states with SXPS. The bulk Si(2p) binding energy for Si(111) is 99.3 eV and the bulk Si(2p) oxide value for film thickness 30 A SiO2 is 103.7eV. 1 The binding energies of the three interface-shifted peaks are intermediate between these values. These have been assigned by Himpsel et al. 2 as the intermediate oxidation states of Si atoms usually labeled Si1+, Si2+ and Si3+ with the bulk Si peak labeled SiO and the bulk oxide peak labeled Si4+. BeamlineU4A has just completed the first phase of a major upgrade. As part of the DOE Facilities Initiative, we are adding spherical gratings and a movable exit slit to the beamline, replacing the toroidal gratings and fixed slits to achieve a spherical toroidal grating monochromator (STGM). More detailed information has become a vital concern in correlators photoemission studies that were started a few years ago. For example, the reconstruction of Si surfaces results in poorly resolved surface-atom core-electron binding-energy shifts that are not readily determined without reliable information about the instrumental width.
Book Synopsis Spectroscopy of Complex Oxide Interfaces by : Claudia Cancellieri
Download or read book Spectroscopy of Complex Oxide Interfaces written by Claudia Cancellieri and published by Springer. This book was released on 2018-04-09 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the most recent and compelling experimental results for complex oxide interfaces. The results of this book were obtained with the cutting-edge photoemission technique at highest energy resolution. Due to their fascinating properties for new-generation electronic devices and the challenge of investigating buried regions, the book chiefly focuses on complex oxide interfaces. The crucial feature of exploring buried interfaces is the use of soft X-ray angle-resolved photoemission spectroscopy (ARPES) operating on the energy range of a few hundred eV to increase the photoelectron mean free path, enabling the photons to penetrate through the top layers – in contrast to conventional ultraviolet (UV)-ARPES techniques. The results presented here, achieved by different research groups around the world, are summarized in a clearly structured way and discussed in comparison with other photoemission spectroscopy techniques and other oxide materials. They are complemented and supported by the most recent theoretical calculations as well as results of complementary experimental techniques including electron transport and inelastic resonant X-ray scattering.

Download or read book Semiconductor Interfaces: Formation and Properties written by Guy LeLay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The trend towards miniaturisation of microelectronic devices and the search for exotic new optoelectronic devices based on multilayers confer a crucial role on semiconductor interfaces. Great advances have recently been achieved in the elaboration of new thin film materials and in the characterization of their interfacial properties, down to the atomic scale, thanks to the development of sophisticated new techniques. This book is a collection of lectures that were given at the International Winter School on Semiconductor Interfaces: Formation and Properties held at the Centre de Physique des Rouches from 24 February to 6 March, 1987. The aim of this Winter School was to present a comprehensive review of this field, in particular of the materials and methods, and to formulate recom mendations for future research. The following topics are treated: (i) Interface formation. The key aspects of molecular beam epitaxy are emphasized, as well as the fabrication of artificially layered structures, strained layer superlattices and the tailoring of abrupt doping profiles. (ii) Fine characterization down to the atomic scale using recently devel oped, powerful techniques such as scanning tunneling microscopy, high reso lution transmission electron microscopy, glancing incidence x-ray diffraction, x-ray standing waves, surface extended x-ray absorption fine structure and surface extended energy-loss fine structure. (iii) Specific physical properties of the interfaces and their prospective applications in devices. We wish to thank warmly all the lecturers and participants, as well as the organizing committee, who made this Winter School a success.
Book Synopsis Zirconia-germanium Interface Photoemission Spectroscopy Using Synchrotron Radiation by :
Download or read book Zirconia-germanium Interface Photoemission Spectroscopy Using Synchrotron Radiation written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An ultrathin zirconia gate dielectric had been successfully incorporated into germanium metal-oxide-semiconductor (MOS) devices demonstrating very high permittivity gate stacks with no apparent interfacial layer. In this study, synchrotron radiation photoemission spectroscopy has been applied on the same gate stack to identify and quantify the presence of any interfacial germanium sub-oxide layer. By taking progressive core- level spectra during the layer-by-layer removal of the zirconia film, an oxidized germanium layer with sub-monolayer thickness was found possibly arising from an interfacial Zr-O-Ge bonding configuration. In addition, the offsets in the valence band spectra were also monitored and the energy band diagram of the zirconia-germanium heterostructure was constructed. Compared to high-[kappa] gate stacks on Si, the thinner interfacial layer and larger conduction band offset in high-[kappa] gate stacks on Ge suggest better scalability towards an ultimately higher MOS gate capacitance.

Download or read book Advanced Synchrotron Radiation Techniques for Nanostructured Materials written by Chiara Battocchio and published by MDPI. This book was released on 2019-10-29 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanostructured materials exploit physical phenomena and mechanisms that cannot be derived by simply scaling down the associated bulk structures and phenomena; furthermore, new quantum effects come into play in nanosystems. The exploitation of these emerging nanoscale interactions prompts the innovative design of nanomaterials. Understanding the behavior of materials on all length scales—from the nanostructure up to the macroscopic response—is a critical challenge for materials science. Modern analytical technologies based on synchrotron radiation (SR) allow for the non-destructive investigation of the chemical, electronic, and magnetic structure of materials in any environment. SR facilities have developed revolutionary new ideas and experimental setups for characterizing nanomaterials, involving spectroscopy, diffraction, scatterings, microscopy, tomography, and all kinds of highly sophisticated combinations of such investigation techniques. This book is a collection of contributions addressing several aspects of synchrotron radiation as applied to the investigation of chemical, electronic, and magnetic structure of nanostructured materials. The results reported here provide not only an interesting and multidisciplinary overview of the chemicophysical investigations of nanostructured materials carried out by state-of-the-art SR-induced techniques, but also an exciting glance into the future perspectives of nanomaterial characterization methods.
