The thermal conductivity and heat capacity of single-crystal Si under hydrostatic pressure

• The thermal conductivity λ and heat capacity ρcP per unit volume of single-crystal Si have been measured under hydrostatic pressure up to 1 GPa at room temperature. The thermal conductivity was found to increase slightly with increasing pressure. For the volume dependence of λ expressed in terms of the Bridgman parameter g=-( δ(ln λ )/ δ(ln V))T, the authors obtained g=0.4. The specific heat capacity cP, calculated from their measured ρcP, was found to be constant against pressure.
