TEMPERATURE-DEPENDENCE OF THE HALL-MOBILITY OF N-TYPE 3C-SIC

The Hall mobility of n-type 3C-SiC has been calculated employing a set of hydrodynamic balance equations. The acoustic, polar optical, piezo electric, and intervalley optical lattice scattering, as well as the i onized and neutral impurity scattering are considered in the transport study. The calculated Hall mobility is in good agreement with the exp erimental data from 70 K to 1000 K. The Hall factor is shown to be les s than unity, due to the nonparabolicity of the energy bands.
