Thermal Conductivity of AlAs(0.07)Sb(0.93) and Al(0.9)Ga(0.1)As(0.07)Sb(0.93) Alloys and (AlAs)1/(AlSB)11 Digital-Alloy Superlattices

Abstract

A differential 3 omega technique is employed to determine the thermal conductivity of the AlAs0.07Sb0.93 ternary alloy, the Al0.9Ga0.1As0.07Sb0.93 quaternary alloy, and an (AlAs)1 /(AlSb)11 digital-alloy superlattice. Between 80 and 300 K, the thermal conductivities for all three samples are relatively insensitive to temperature. The thermal conductivity of the (AlAs)1 /(AlSb)11 superlattice is smaller than that of the AlAs0.07Sb0.93 ternary alloy, but much larger than the predictions of a model for phonon transport across the superlattice interfaces.
