Specific Heats of GaSb, GaAs, InSb, InAs, Bi, Cd, Sn, and Zn below 30 K

Abstract

Previously reported heat-capacity data from 1 to 30 K for four III-V compounds and four anisotropic metals have been reanalysed using a magnetically smoothed temperature scale ($T_x$). Values are given for the contributions due to free carriers in the III-V compounds and electrons in the metals, and for the lattice contributions to the specific heats at low temperatures. Excellent agreement is obtained between calorimetric and elastic-constant determinations of the limiting Debye temperature at $T=0\mathrm{}$.
