Diffusion and mobility of native point defects in narrow-gap Hg₁-xCdxTe crystals

Results of investigations of mercury vacancy diffusion in the narrow-gap Hg₁-xCdxTe crystals are presented. A new theory for mercury diffusion in a gradient of native defect concentration is proposed. The theory takes into account the effect of charged defect drift in the internal electric field ari...
