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 ...
The unique transport properties make CuInTe2 emerge as a promising thermoelectric material. However, the intrinsically low carrier concentration and high lattice thermal conductivity of CuInTe2 limit its thermoelectric performance. In this work, firstly, we investigate the influence of excess Te on the...

The CuInTe2 nanocrystals can be obtained either with microwave irradiation [21,22], by solvothermal synthesis [23], or by using a silicate matrix method [19]. However, by using these methods, the CuInTe2 was heavily aggregated and could not be well dispersed and; thus, could not be used...
