Quantum Kinetic Theory of the '2k_F' Scattering Mechanism for Three-Dimensional Structurally Disordered Systems in the Ioffe-Regel limit

Abstract

Eect of the coherent backscattering of the conduction electrons in three-dimensional structurally disordered metals specied by the IoeRegel criterion is considered within the framework of the MorganHowsonaub theory of localisation which is based on the generalised kinetic equation for the Wigner distribution function and eective medium approximation. A formula for the electrical resistivity including the weak localisation correction is expressed in terms of the dimensionless transport parameter kF . The asymptotic form of the formula is derived and discussed in the context of the diagrammatic approach.
