Statistical relaxation

The simulation finds a large number of vacancy-simplexes, which plays a role of diffusion vehicle for cobalt atom and varies with relaxation degree. A new diffusion mechanism for tracer diffusivity in cobalt amorphous solid is supposed as follows: The elemental atomic movement includes a jump of neighbouring atoms into the vacancy-simplexes and then collective displacement of a large number of atoms.

The effects of strain on the diffusion of impurities in silicon crystal are investigated using the statistical moment method (SMM). The influence of tensile strain on diffusion coefficient D is characterized by relaxation volume V r and migration volume V m. The numerical results for B and P diffusion in silicon that are performed and compared to experimental data show good agreement.
