Boundary conditions for distribution functions at interfaces between crystalline grains

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The paper concerns a derivation of boundary conditions at a planar interface between two crystalline grains for distribution functions of quasiparticles of a given kind. The derivation is performed under the assumption that the equi-energy surfaces (in thek-space) which, in general, need not be the same in both the grains, are convex. The boundary conditions take into account a jump of the (electro) chemical potential and temperature induced when a current of the quasiparticles passes through the interface. The Bezák-Krempaský boundary conditions that were originally formulated for longitudinal currents are thus generalized to the case when the currents may have a transversal component.
