High-temperature heat contents, thermal diffusivities, densities, and thermal conductivities of n-type SiGe(GaP), p-type SiGe(GaP), and p-type SiGe alloys

Abstract

The high-temperature heat contents of n-type SiGe(GaP), p-type SiGe(GaP), and p-type SiGe alloys were measured from 400 to 1400 K by using a copper block drop calorimeter. The heat capacity and related thermodynamic functions were calculated. Smoothed values of H0T−H0298.15, Cp, S0T−S0298.15, and −(F0T−H0298.15)T−1 were tabulated at 100-K intervals. Thermal diffusivities were measured by using a laser technique. Thermal conductivities were calculated from the heat capacity, thermal diffusivity, and density.
