Abstract
A microscopical theory is developed which describes the non-steady kinetic phenomena (e.g. conduction and diffusion) for defectons in a crystal. The principal features of the phenomena, the effects of the lattice deformation and the many-level nature of the defecton potential wells are discussed and expressions for the conductivity and diffusion coefficient for free and bound defectons are obtained. The role of the coherent and incoherent underbarrier and overbarrier transitions is explained. The quasiclassical case of non-steady diffusion and Debye-type and resonance type dielectric losses are compared with classical results and the effects of strong external or random internal fields are noted.
