摘要
Pressure-dependent resistivity and Hall effect measurements indicate that p - type Cd1 - xMnx GeAs2 solid solutions with x = 0.06 and 0.18 undergo a high-pressure semiconductor-metal transition. The characteristic points of the phase transition are located, and its dynamics is analyzed in terms of the theory of mixed-phase systems.
