Debye θ of Hexagonal Crystals at 0°K

Abstract

A set of numerical tables is given which permits the easy calculation of the Debye characteristic temperature at 0°K of any crystal with hexagonal symmetry. The use of the tables presupposes a knowledge of the elastic constants, atomic volume, and density of the crystal. Values of the characteristic temperature obtained with the use of the tables are compared with those obtained by direct calculation in a number of special cases.
