The dark alternating current (ac) parameters of ZnSe/ZnTe/CdTe thin films heterostructures are measured at different temperatures using the impedance spectroscopy. The real and imaginary parts of the complex impedance are changed with the frequency and temperature. Both are decreased with increasing temperature at the lower frequencies and are merged at the higher frequencies. The dielectrical relaxation mechanism of the heterostructure was analyzed by the Cole-Cole plots. With increasing temperature, the radius of the Cole-Cole plots decreases, which suggests a mechanism of temperature-dependent on relaxation. |
