ABSTRACTThe compensation mechanism and transport properties of annealed GaAs grown by molecular beam epitaxy at low substrate temperature (LT-GaAs) and Cu diffused InP are analyzed by using a deep donor band model and a precipitate model. It was found that the compensation in highly resistive LT GaAs can not be explained by the precipitate model alone, and therefore a high donor density had to be considered. In Cu diffused InP, the precipitate model gives a consistent explanation for the observed carrier compensation and mobility data. For both semi-insulating LT-GaAs and fully-compensated, lightly-doped InP:Cu, the neutral impurity scattering was found to be a major carrier scattering mechanism.

The Hall mobility in n-type 4H-SiC has been calculated by hydrodynamic balance equations for temperatures ranging from 30 to 1000 K. We employ a compensation model to analyze the carrier concentration versus temperature data. The results show that the neutral impurity scattering and the piezoelectric scattering do not make significant contribution to the electron mobility. The low-temperature value of the mobility is mainly due to the ionized impurity while the high-temperature tail is limited by acoustic, polar optical and intervalley optical lattice scatterings. These results are in good agreement with the experimental data.
