Abstract

It is known^1,2 that atomic particles may migrate by coherent tunneling between its localized states in host lattices at low temperature, whereas at higher temperature phonon interactions promote a range of other migration paths ranging from incoherent tunneling to thermally excited over-the-barrier jumps. As a rule, quantum tunneling effects are unimportant in semiconductors at temperatures where diffusion measurements are practicable and thermal diffusion of impurities is considered.
