The strange diffusivity of Ag atoms in CdTe

The diffusion of Ag atoms in CdTe was investigated using the radiotracer $^{111}\!$Ag, which was introduced by implantation with an energy of 60 or 80 keV. The measured diffusion profiles are explained by assuming the existence of a repulsive interaction between Ag and residual Cu atoms causing a dr...

description The diffusion of Ag atoms in CdTe was investigated using the radiotracer $^{111}\!$Ag, which was introduced by implantation with an energy of 60 or 80 keV. The measured diffusion profiles are explained by assuming the existence of a repulsive interaction between Ag and residual Cu atoms causing a drift of the Ag atoms towards the centre of the crystal, which supposes the diffusion in a concentration gradient. This effect vanishes if the Ag concentration is increased and becomes more pronounced if the crystals are simultaneously co- doped with Cu. (11 refs).
