ABSTRACT
A simple method of Eg(T) dependence determination for active areas of semiconductor devices based on wide bandgap semiconductors has been proposed and developed. Verification of the method has been carried out while determining Eg(T) dependence in a base area of p+-n-type GaP diodes in the temperature range 77-523 K. The method is based on U-T characterization of the diodes and calculation of Eg(T) dependence according to the expression obtained within present study. Satisfactory agreement between experimental and theoretical results has been achieved including references available on gallium phosphide. The method proposed could be applied to experimental data processing in high-temperature thermometry.

    During the past few decades, silicon carbide (SiC) has emerged as the most promising wide-bandgap semiconductor for high-temperature, high-frequency, and high-power applications. All its attractive properties depend critically on and are often limited by the formation of Ohmic contacts to SiC....

    On the basis of relativistic ab initio calculations, we show that both Te- and I-terminated surfaces of the polar layered semiconductor BiTeI hold surface states with a giant Rashba-type spin splitting. The Te-terminated surface state has nearly isotropic free-electron-like dispersion with a...
