CuInTe2 is considered a promising thermoelectric material due to its intrinsic high Seebeck coefficient and relatively low thermal conductivity. However, due to its low carrier concentration, despite elaborate strategies such as doping, composites, and second-phase engineering having been developed, ...
Photoluminescence studies of chalcopyrite CuInTe2 were conducted. Three edge (1.041 eV, 1.030 eV, and 1.019 eV) and two deep level (0.999 eV and 0.957 eV) emission bands were observed at 11 K. The excitation intensity dependence of PL spectra was recorded. As possible band sources one ...

CuInTe2 and CuInSe2 are direct bandgap ternary chalcopyrite (I-III-VI2) semiconductors which are the simplest ternary analogs of the II-VI zincblende compounds. Some of the chalcopyrites exhibit nonlinear optical properties which make them good candidates for optical device technology. We have done...
