Available in PDF, EPUB and Kindle. Book excerpt: This research addresses the need for fundamental information concerning halogen etching of III-V semiconductors. The reactions of halogens with semiconductor surfaces are the fundamental chemical interactions in processes employed for device manufacture. In this work, the reactions of XeF2, Cl2 and I2 with III-V semiconductor surfaces were investigated with synchrotron-based soft x-ray photoelectron spectroscopy, low energy electron diffraction and scanning tunneling microscopy. Fluorine reaction grows films of group III fluorides, which can be used as dielectric materials. Chlorine is the most widely used halogen for dry etching, while iodine has been proposed for use as a "gentle" etchant. We found that, for all of the halogen reactions, the initial adsorption depends on the surface reconstruction, stoichiometry and condition. Some surfaces passivate, while others spontaneously etch at room temperature. The passivated surfaces are well-ordered and covered with approximately one monolayer of adsorbed halogen. The etched surfaces, on the other hand, are considerably rough and atomically disordered. A microscopic model is proposed which assumes that halogen atoms preferentially adsorb onto a group III atom if the surface is initially well-ordered. This microscopic model can explain why certain surfaces etch, while others form ordered overlayers.

Available in PDF, EPUB and Kindle. Book excerpt: We are at a critical evolutionary juncture in the research and development of low-temperature plasmas, which have become essential to synthesizing and processing vital nanoscale materials. More and more industries are increasingly dependent on plasma technology to develop integrated small-scale devices, but physical limits to growth, and other challenges, threaten progress. Plasma Processing of Nanomaterials is an in-depth guide to the art and science of plasma-based chemical processes used to synthesize, process, and modify various classes of nanoscale materials such as nanoparticles, carbon nanotubes, and semiconductor nanowires. Plasma technology enables a wide range of academic and industrial applications in fields including electronics, textiles, automotives, aerospace, and biomedical. A prime example is the semiconductor industry, in which engineers revolutionized microelectronics by using plasmas to deposit and etch thin films and fabricate integrated circuits. An overview of progress and future potential in plasma processing, this reference illustrates key experimental and theoretical aspects by presenting practical examples of: Nanoscale etching/deposition of thin films Catalytic growth of carbon nanotubes and semiconductor nanowires Silicon nanoparticle synthesis Functionalization of carbon nanotubes Self-organized nanostructures Significant advances are expected in nanoelectronics, photovoltaics, and other emerging fields as plasma technology is further optimized to improve the implementation of nanomaterials with well-defined size, shape, and composition. Moving away from the usual focus on wet techniques embraced in chemistry and physics, the author sheds light on pivotal breakthroughs being made by the smaller plasma community. Written for a diverse audience working in fields ranging from nanoelectronics and energy sensors to catalysis and nanomedicine, this resource will help readers improve development and application of nanomaterials in their own work. About the Author: R. Mohan Sankaran received the American Vacuum Society’s 2011 Peter Mark Memorial Award for his outstanding contributions to tandem plasma synthesis.

Download or read book Hydrogen-Halogen Chemistry on Semiconductor Surfaces written by and published by . This book was released on 1992 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of coadsorbed H and X (X=Cl, Br) on semiconductor surfaces is important in epitaxial growth of silicon from chlorosilanes and of Si(x)Ge(1-x) alloys, in hydrogenating/halogenating cycles in atomic layer epitaxy, and also provides an interesting model system, yet has received little attention to date. We have investigated the interaction of H, HCl, and HBr with Ge(100) by temperature-programmed desorption, and find that H2, HCl, and HBr each absorb with near-first-order kinetics near 570-580 K, and the GECL2 and GeBr2 desorb with second-order kinetics near 680 K and 710 K, respectively. Trends in the chemistry and kinetics can be rationalized by viewing the dimer atoms on clean Ge(100)-(2x1) as being linked by a strained double bond and adsorption, decomposition, and desorption as being analogous to addition, rearrangement, and elimination reactions of molecular germanium compounds. The near-first-order desorption kinetics are attributed to pairing on surface dimers induced by the pi bond on unoccupied dimers. We infer a pairing enthalpy for H+H (=the pi bond strength of dimerized Ge(100) surface atoms) of 4-5 kcal/mol.

The discussions are initialized with an introduction; identification of factors that influence metal-metal bond formation; and compounds that contain multi-centred metal-metal bonds. The text also looks at the nature of metal-halogen bonds and the metal-halogen vibrational frequencies. Numerical representations and tabulations are presented as well. The book also looks at the halides of niobium and tantalum. Concerns include fluorine, chlorine, bromine, and iodine compounds. The compilation further considers pentahalides of transition metals and halide chemistry of chromium, molybdenum, and tungsten. The book closes with discussions on halogen chemistry of actinides and halogeno metal carbonyls and related compounds. Covered areas include trivalent, tetravalent, pentavalent, and hexavalent actinides, and structures and reactions of halogeno metal carbonyls. The compilation is a valuable source of information for readers interested in the study of halogens.

This book was released on 2012-12-06 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Advanced Study Institute on the Electronic Properties of Multilayers and Low Dimensional Semiconductor Structures focussed on several of the most active areas in modern semiconductor physics. These included resonant tunnelling and superlattice phenomena and the topics of ballistic transport, quantised conductance and anomalous magnetoresistance effects in laterally gated two-dimensional electron systems. Although the main emphasis was on fundamental physics, a series of supporting lectures described the underlying technology (Molecular Beam Epitaxy, Metallo-Organic Chemical Vapour Deposition, Electron Beam Lithography and other advanced processing technologies). Actual and potential applications of low dimensional structures in optoelectronic and high frequency devices were also discussed. The ASI took the form of a series of lectures of about fifty minutes' duration which were given by senior researchers from a wide range of countries. Most of the lectures are recorded in these Proceedings. The younger members of the Institute made the predominant contribution to the discussion sessions following each lecture and, in addition, provided most of the fifty-five papers that were presented in two lively poster sessions. The ASl emphasised the impressive way in which this research field has developed through the fruitful interaction of theory, experiment and semiconductor device technology. Many of the talks demonstrated both the effectiveness and limitations of semiclassical concepts in describing the quantum phenomena exhibited by electrons in low dimensional structures.

Available in PDF, EPUB and Kindle. Book excerpt: Between the area known as surface science (which mainly deals with single crystal surfaces) and the vast area of the surface properties of dispersed solids (knowledge of which is widely applied in catalysis and materials science) there is still a remarkably wide, although gradually decreasing, gap. Because fundamental physico-chemical problems are involved, this borderline area needs to be explored. With this objective, the Trieste meeting brought together specialists with a variety of origins and backgrounds, with the aim of stimulating the growth of our knowledge in this area.This proceedings volume contains ninety-three papers, comprising plenary lectures, short communications, and poster contributions on the applications of physical and theoretical methods to perfect and dispersed (microcrystalline and amorphous) metals, oxides, and mixed systems. Special emphasis is given to metal-support interfaces.The book thus provides a wealth of up-to-date information on a topic of current interest which will be of value to researchers who use chemical and/or physical methods for the study of surfaces.
