Electronic Properties of Metals

Download or read book Electronic Properties of Metals written by Gerd Lehmann and published by Elsevier Publishing Company. This book was released on 1990 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The excitation spectrum or band structure of electronics is often interpreted as the electronic structure. This definition is based on the Landau theory of elementary excitations, which shows that the reaction of a many-particle system on a weak external perturbation can be described by nearly non-interacting low-energy excitations of one-particle type. In metals these excitations close to the Fermi energy are only lightly damped. On this basis many electronic properties, especially of metals, can be understood and calculated, a breakthrough which has made a considerable contribution to materials science. This book focuses on the basic principles of solid state physics and in particular on actual problems and recent applications which have not previously been reviewed. At present a common electron theory for all types of solids is developing, unifying the viewing and treatment of the electronic structure and electronic properties of metals and semiconductors.
