Determination of Electronic States in Crystalline Semiconductors and Metals by Angle-resolved Photoemission


Book Description

An important part of the theoretical description of the solid state is band structure, which relies on the existence of dispersion relations connecting the electronic energy and wavevector in materials with translational symmetry. These relations determine the electronic behavior of such materials. The elaboration of accurate band structures, therefore, is of considerable fundamental and practical importance. Angle-resolved photoemission (ARP) spectroscopy provides the only presently available method for the detailed experimental investigation of band structures. This work is concerned with its application to both semiconducting and metallic single crystals.










Angle-Resolved Photoemission


Book Description

Angle-resolved photoemission has become an indispensable tool for solid state and surface physicists and chemists. This book covers the underlying phenomenology of the technique, reviews its application to existing problems, and discusses future applications. The book is particularly timely given the significant improvements in experimental and theoretical methodology which have recently been or soon will be attained, namely, ultrahigh resolution studies using improved sources of synchrotron radiation, quasiparticle interpretation of measured dispersion relations and spectra, in situ growth of novel materials, etc. The technique has been applied predominantly to understand materials for which the one-electron paradigm is a reasonable approximation. Most chapters discuss this type of experiment: 2D and 3D states in metals and semiconductors, extrinsic states induced by adsorption, etc. Applications of the technique to materials where electron correlation plays a comparable role to that of solid state hybridization, ferro- and antiferromagnets, high Tc superconductors, etc. are rapidly growing in popularity. These areas are also discussed and a foundation is laid for further experiments in this direction. Almost all chapters contain comprehensive bibliographies and compendia of systems studied. The book has an extensive index which cross references applications and systems studied.







Solid-State Photoemission and Related Methods


Book Description

Photoemission is one of the principal techniques for the characterization and investigation of condensed matter systems. The field has experienced many developments in recent years, which may also be put down to important achievements in closely related areas. This timely and up-to-date handbook is written by experts in the field who provide the background needed by both experimentalists and theorists. It represents an interesting framework for showing the connection between theory and experiment by bringing together different concepts in the investigation of the properties of materials. The work addresses the geometric and electronic structure of solid surfaces and interfaces, theoretical methods for direct computation of spectra, experimental techniques for data acquisition, and physical models for direct data interpretation. It also includes such recent developments as full hemisphere acceptance in photoemission, two-electron photoemission, (e, 2e) electron diffraction, and photoelectron-electron/hole interaction.




Surfaces and Interfaces: Physics and Electronics


Book Description

Surfaces and Interfaces: Physics and Electronics covers the proceedings of the second Trieste ICTP-IUPAP Semiconductor Symposium, conducted at the International Center for Theoretical Physics in Trieste, Italy on August 30 to September 3, 1982. The book focuses on the processes, methodologies, reactions, and approaches involved in semiconductor physics. The selection first elaborates on the electronic properties and surface geometry of GaAs and ZnO surfaces; electronic structure of Si (III) surfaces; and photoemission studies of surface states on Si (III) 2X1. Discussions focus on consistency of different experiments, relating experiments to a theoretical model, quenching of surface states by hydrogen, inverse photoemission results, and basic data and models of the low-index ZnO surfaces. The text then examines Si (III) 2X1 studies by angle resolved photoemission; electronic surface states at steps in Si (III) 2X1; and a novel method for the study of optical properties of surfaces. The manuscript takes a look at spot profile analysis (LEED) of defects at silicon surfaces; chemisorption-induced defects at interfaces on compound semiconductors; and surface defects on semiconductors. The microscopic properties and behavior of silicide interfaces, recombination at semiconductor surfaces and interfaces, and dipoles, defects, and interfaces are also discussed. The selection is a highly recommended source of data for physicists and readers wanting to study semiconductor physics.

Electronic Properties Of Dirac And Weyl Semimetals


Book Description

The monograph reviews various aspects of electronic properties of Dirac and Weyl semimetals. After a brief discussion of 2D Dirac semimetals, a comprehensive review of 3D materials is given. The description starts from an overview of the topological properties and symmetries of Dirac and Weyl semimetals. In addition, several low-energy models of Dirac and Weyl quasiparticles are presented. The key ab initio approaches and material realizations are given. The monograph includes detailed discussions of the surface Fermi arcs, anomalous transport properties, and collective modes of Dirac and Weyl semimetals. Superconductivity in these materials is briefly addressed.
