Abstract:
The transport properties of n-CdAs2 have been studied under increasing and decreasing hydrostatic (p a parts per thousand currency sign 9 GPa) and quasi-hydrostatic (p a parts per thousand currency sign 50 GPa) pressures. We have identified three phase transitions in n-CdAs2 and two phase transitions in p-ZnAs2. According to temperature-dependent resistivity data, the conductivity of the materials is determined by activation mechanisms in the temperature range 250-400 K, with a temperature-dependent activation energy. We have obtained pressure dependences of the activation energy and coefficient R (0), which characterizes the carrier mobility, concentration, and effective mass.
