Abstract

Self-diffusion in intrinsic single crystalline germanium was investigated between 429 and 596 degrees C using (70)Ge/(nat)Ge isotope multilayer structures. The diffusivities were determined by neutron reflectometry from the decay of the first and third order Bragg peak. At high temperatures the diffusivities are in excellent agreement with literature data obtained by ion beam sputtering ...
