The n-type sample is obtained by annealing p-type CuInTe2 in the presence of indium for a prolonged period of time. The p-type samples are grown by programmed directional freezing technique with slight excess of indium in the stoichiometry. Two defect levels with ED = 58 meV and EA around 15 meV are identified from the analysis of the temperature dependence of the carrier concentration. The origin of these levels, consistent with the covalent bonding model, is attributed to InCu and VTe, respectively. From a theoretical fit to the experimental data, the density of states effective mass of the electrons is found to be m = 0.16me. The estimated values of the conduction and valence-band deformation potentials are in agreement with the general trend observed in other I–III–VI2 compounds. Using the model proposed for the band-gap shrinkage, the energy gap of n-type CuInTe2 in the dilute limit is calculated to be 1.026 eV. On a etudie les proprietes electriques entre 80 et 300 K, et l'absorption optique a temperature ambiante de CuInTe2 type n et type p.

Outside the core a sum of Coulomb and Yukawa potential is taken as a perturbation in the MSM approximation. The partial structure functions are computed by means of Pearson-Rushbrooke relations. Using these PSF's the radial distribution functions are calculated. All these partial structure functions have equal positive values at the long wave limit and the oscillations of the total direct correlation functions are found to cease with increasing k as expected. This new method is a generalization of previous MSM results in the sense that more general forms for the direct correlation function are considered. In both the cases, the coefficients of all terms can be independently adjusted. The partial structure functions and the radial distribution functions so computed gives better agreement than the mean spherical model approximation with experimental and also with molecular dynamics calculations. \u0000 \u0000 \u0000 \u0000Es wird die verallgemeinerte „Mean-Spherical-Model-Approximation„ benutzt, um die direkte Gesamtkorrelationsfunktion zu erhalten, mittels einer Losung die der von Waisman-Lebowitz (WL) im Rumpfinneren ahnlich ist. Auserhalb des Rumpfes wird eine Summe des Coulomb- und Yukawa-Potentials als Storung der MSM-Naherung angenommen. Die Partial-Strukturfunktionen werden mittels Pearson-Rushbrooke-Beziehungen berechnet. Mit diesen PSF werden dann die radialen Verteilungsfunktionen berechnet. Alle Partial-Strukturfunktionen haben gleiche positive Werte im Grenzfall langer Wellen und es wird gefunden, das die Oszillationen der direkten Gesamtkorrelationsfunktionen, wie erwartet, mit wachsendem k geringer werden. Diese neue Methode ist eine Verallgemeinerung fruherer MSM-Ergebnisse in dem Sinne, das allgemeinere Formen fur die direkte Korrelationsfunktion betrachtet werden. In beiden Fallen lassen sich die Koeffizienten aller Terme unabhangig anpassen.
