Abstract

Effect of iso-valency doping with S, Se or Zn dopants on Hg_1-xCd_xTe mechanical, structural and photoelectric properties is considered. It was revealed that iso-valency doping reduced the etch pit density and increased the microhardness in Hg_1-xCd_xTe single crystals. Such doping also improved the photoelectric properties, especially increased the excess carrier lifetime. Taking into account the value of equilibrium concentration of S, Se and Zn iso-valency dopants in Hg_1-xCd_xTe single crystals it was concluded that the most suitable iso-valency dopant is Se.
