Abstract

Diffusion lengths of minority electrons and holes in Hg_1-xCd_xTe single crystals produced by the diffusion controlled Bridgman growth from melt of constant composition were studied. Bulk p-HgCdTe samples were etched by low energy Ar ions in the VEECO ion etching system or in Ar plasma in a plasma etching reactor. As a result of this treatment a deep p-n junction was created in the samples. Secondary-electron and electron beam induced current images were used to determine the position of the p-n junction. The obtained EBIC data were then sued for evaluation of a set of minority carrier diffusion lengths at temperatures 140-270 K.
