Abstract:	Using the statistical moment method, self-diffusion in semiconductors is studied including the anharmonic effects of lattice vibrations. The interaction energies between atoms in semiconductors are estimated by applying many-body potential. The activation energy Q and pre-exponential factor D{) of the self-diffusion coefficient are given in closed forms. The values of Q and D0 are calculated for Si and GaAs at high temperature region near the melting temperatures and they shown to be in good agreement with the experimental data.
