Carrier concentration and mobility in two-phase eutectic A/sup III/B/sup V/-Ge(Si) alloys
The authors proposes a technique of determining the carrier concentration and mobility in the separate phases of two-phase alloys in which oriented rod-like inclusions have carrier concentrations similar to the host material. The calculations are then used to determine the carrier concentration and mobility in each alloy phase, and to discuss the doping processes and mechanisms of impurity incorporation in two-phase semiconductors. He studied the Hall constant R in two-phase, oriented eutectic alloys of InSb-Ge, InAs-Ge, GaAs-Ge, and GaAs-Si. He established that R depends on the relative orientations of the current flow, magnetic field, and elongated inclusions. Furthermore, the particular impurity concentration in the alloy also has an effect on R.
