英文摘要: Abstract(#br)Zinc diffusion process in N-GaSb was studied with excessive, appropriate and insufficient quantity of diffusion source (zinc pellets). Kink-and-tail type zinc concentration profiles obtained with appropriate zinc pellets quantity were successfully simulated using the assumption that the vacancy mechanism mediated by V Ga 0 and kick-out mechanism mediated by I Ga + take effect at the same time. It is found out that for diffusion temperature from 460°C to 500°C, the zinc surface concentration of the diffused samples has nearly no change and the logarithmic value of the zinc surface diffusion coefficient is linear with the reciprocal value of diffusion temperature; when the diffusion temperature is constant, both the zinc surface concentration and diffusion coefficient do not...
