Correlation between the bulk modulus and the transition pressure in semiconductors

Abstract

The correlation between the bulk modulus B 0 and the transition pressure in semiconductors was analyzed. The transition pressure from zinc blende to β-Sn structure was used to calculate the bulk modulus. It was found that for the II-VI semiconductors, the differences between the experiment and the calculated values were less than 5% except for CdS and CdTe where the coincidence and emergence cases happened. It was also found the calculated estimations were larger than the measured values for the III-VI semiconductors except for GaP, and the tendency was similar for the II-VI semiconductors.
