Abstract

This paper discusses the possibility of a hopping carrier giving rise to dielectric absorption. It is conjectured that the dielectric absorption in amorphous materials should be attributed to correlation between jumps of the carriers. In the simplified model proposed, the carrier, after arriving at a given lattice site, may choose between subsites, this limited degree of freedom leading to a polarization process in the presence of an electric field. This polarization is discontinued when the particle makes a jump to a new lattice site, where the polarization is relaxed. The Debye relaxation law is obtained as a limiting case.
