The theory of how metals conduct electronically had for a long time been confined to metals that are crystalline with the constituent atoms in regular arrays. The discovery of how to make solid amorphous alloys led to an explosion of measurements of the electronic properties of these new materials, and the emergence of a range of interesting low temperature phenomena. This 1995 book describes in physical terms the theory of the electrical conductivity, Hall coefficient, magnetoresistance and thermopower of disordered metals and alloys. The author begins by showing how conventional Boltzmann theory can be extended and modified when the mean free path of the conduction electrons becomes comparable with their wavelength and interionic separation. The consequence of this is explored and the theory tested by application to experimental data on metallic glasses. Designed as a self-contained review, the book will appeal to non-specialist physicists, metallurgists and chemists with an interest in disordered metals.
Using many-particle perturbation theory an attempt has been made to improve the author's previous calculation of the thermal expansion of sodium chloride and to assess the effect of including anharmonic terms in the crystal potential. The results are disappointing; agreement with experiment is poor except at low and moderate temperatures. One reason for this is the poor convergence of a method based on the series expansion of the crystal potential in terms of particle displacements, 8 point further. illustrated by calculations of specific heat and compressibility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
