THERMAL EXPANSION OF SOLIDS AND THE TEMPERATURE DEPENDENCE OF LATTICE VIBRATION FREQUENCIES
Keyword(s):
It is shown that a close relation exists between the temperature coefficient of lattice vibration frequencies and the thermal expansion coefficient. The basic equations[Formula: see text](νi being the frequency of the ith mode of vibration, T the temperature, Ci the Einstein function of frequency νi, γ the Grueneisen parameter, and β the volume thermal expansion coefficient) are derived and discussed for various temperature ranges.
