| الوصف: | We report a method for a new classification procedure for liquid-phase epitaxially grown mercury cadmium telluride single crystals. Variable-magnetic-field Hall measurements are performed on nine liquid-phase epitaxially grown Hg0.78Cd0.22Te single-crystal films for magnetic fields from 0 to 1.4 T and in the temperature range from 10 K to 300 K. The data from these measurements are analysed in the context of the reduced-conductivity-tensor scheme proposed by Kim et al. (1993). Based on the degree of deviation from an ideal one-carrier behaviour, these experimental samples are classified into several types to emphasize the transition in the behaviour of the normal to anomalous n-type samples, finally leading to p-type samples. Our classification is also based on a general trend in the temperature dependence of the mobility and density of the majority carriers, which were extracted from the magnetoresistivity data. The classification provides a useful benchmark for materials characterization in the infrared detector industry. |
