Experimental studies of transport and noise characteristics of CdTe (Cl doped) crystals, prepared by travelling heater method, have been carried out. The basic material is of p-type with p=1.8×1014 m−3, μh=0.0065 m2V−1s−1, μe=0.13 m2V−1s−1. The current and noise spectral density was measured as a function of the sample illumination, voltages across the sample and incident light wavelengths. Two types of effective charge carrier mobility are assumed: namely, the effective transport mobility, which is 0.065 m2V−1s−1 and the effective noise mobility, which reaches a value of 0.125 m2V−1s−1, both for high illumination. Under the same conditions, the density of light generated charge carrier pairs is 1.7×1015 m−3. Experimental results are in a good agreement with the four-level recombination model. The values of 1/f noise parameter α range from 4×10−4 to 2.5×10−3. The α parameter grows with almost the photocurrent square root. The signal-to-noise ratio improves if the electric field strength in the CdTe detector is set to a higher value. |
