Debye Characteristic Temperature at 0°K of Certain Cubic Crystals

Abstract

In an earlier article the author presented a numerical table which permits an easy calculation of the Debye characteristic temperature at 0°K for cubic metallic elements whose elastic constants exhibit the inequality c₁₂>c₄₄. This table has been extended to include some cubic nonmetallic elements whose elastic constants exhibit the inequality c₁₂<c₄₄. The new table has been utilized in the calculation of the characteristic temperatures of diamond, Ge, and Si from their elastic constants.
