Temperature dependent density of states effective mass in nonparabolic p-type silicon

Abstract

Previously, an exact calculation was made for the temperature dependent density of states effective mass in p-type silicon. This calculation was made for the nondegenerate regime and included the full nonspherical-nonparabolic nature of the valence band structure. For those researchers interested in using this mass for the analysis of their transport data we offer a polynomial fitted expression. The values generated are within 1% of the theoretical values.
