The band gap pressure coefficient of CuInTe2 at room temperature has been measured to be 53 meV/GPa in contrast to the value of 22 meV/GPa reported previously by Gonzalez and Rincon (J. Phys. Chem. Solids, 51 (1990) 1093). The new coefficient is in good agreement with the ...
gap shrinkage, the energy gap of n-type CuInTe2in the dilute limit is cal-culated to be 1.026 eV.On a étudié les propriétés électriques entre 80 et 300 K, et l'absorption optique à températureambiante de CuInTe2type n et type p. L'échantillon type n a été obtenu par re...
The CuInTe2 thin films is one of the most attractive semiconductors for solar cells applications, since its direct band gap energy (Eg≈1eV) is suitable as an absorber in photovoltaic conversion. In this letter the CuInTe2 thin films are prepared by flash evaporation technique. X-ray ...
The band gap of Mn:CuInTe2is larger than 0.92 eV. Most samples show phonon‐limited mobility, with the highest mobilities occurring at 75 K. Samples with 3% Mn substitution in Cu sites are paramagnetic. At higher Mn concentration (9%
The crystal structure as well as the optical properties in the band gap region of (CuInTe2)1-x(2 ZnTe)x solid solution single crystals grown by directional freezing have been studied. The lattice constants exhibit a linear dependence on crystal composition. The chalcopyrite-sphalerite phase...

CuInTe2(1-x) S2x thin films were deposited by this method. Optical band gap was determined for composition parameter x from the transmittance study at room temperature. Optical band gap increases as composition x increases and it is varying ...
The optical band gap was found to vary within 0.95–0.97 eV with the variation of the Cu/In ratio within 0.72 to 0.92 while the grain size varied between 0.25 and 0.44 μm. Lattice constants were determined from the X-ray diffraction analysis. The films were polycrystalline in nature a...
The data is used to evaluate the absorption spectra, the band gap energy and ionisation energies of defects that have been observed in the tail of the spectra. The obtained Results confirm the efficiency of the technique in detecting the non-radiative defects known to dominate the properties of...
From an analysis of the optical absorption spectra of the thin films, the band gap of CuInTe 2 is found to be 1.03 eV. The effect of the background absorption on the absorption spectrum is found to be negligible. The electrical conductivity of these films is limited by hopping conduction ...
