摘要

Optical and photoelectric measurements reveal that doping with iron leads to the formation of a deep level at E (c)-0.69 eV in (HgInTe6)-In-3-Te-2 crystals. When light is absorbed by Fe2+ impurity centers, both electronic transitions of the impurity-level-conduction-band type and optical transitions between ground and excited states of the aforementioned centers (intracenter transitions) are observed. Investigations of transport phenomena point to the acceptor properties of Fe2+ centers.
