Opis

The theory of metallic conduction has, until recently, been confined to crystalline metals with atoms in regular arrays. The discovery of solid amorphous alloys led to an explosion of measurements of their electronic properties, and the emergence of a range of interesting low temperature phenomena. The 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. Dugdale explores the consequences of this and tests the theory by applying it to experimental data on metallic glasses. Designed as a self-contained review, the book will appeal to nonspecialist physicists, metallurgists and chemists with an interest in disordered metals.

Recenzje

"...the important ideas and experiments in this book are effectively explained in understandable physical terms and backed up with straight forward calculations. It succeeds in describing the potentially daunting theory of transport in disordered conductors in a highly intuitive way that will appeal very much to beginning graduate or advanced undergraduate students or interested non-experts in physics, materials science, chemistry, or electrical engineering." Nathan Israeloff, Materials Research Bulletin
