Rezumat

CdS/CdTe/Te heterojunction have been studied by capacitance-voltage measurements over the temperature range 293 K-393 K. The potential of diffusion, profile of the ionized-charge concentration in the space charge region of heterojunction and its thickness are derived from the heterojunction capacitance measured at different bias voltages. The charge carrier concentrations calculated from (S/C)2 = f(U) for low and high voltage ranges, respectively are (1-3)·1014 cm-3 and it is associated with the volume concentration of CdTe and (2-5) 1013 cm-3 which corresponds to the region of interface of the CdS/CdTe/.
