The aim of the present note is t o develop a theory of the electroconductivity in disordered. transition metal alloys with a proper microscopic treatment of the electron-phonon interaction (cf. /1 to 3/).F o r a given configuration of atoms the total Hamiltonian of the electronion system in the substitutionally disordered alloy is written in the form where the electron-phonon interaction term in (1) is taken asThe electrical conductivity will be calculated starting with the Kubo ex- In the following we r e s t r i c t ourselves to a diagonal disorder, i. e.
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.
