STRESS-DEPENDENT RAMAN FREQUENCY AND LINEWIDTH IN α-QUARTZ

Abstract

The experimental results of the stress-dependent frequency and linewidth of two E (128 cm−1, 398 cm−1) and three A1 (207 cm−1, 352 cm−1, 466 cm−1) Raman-active vibrations in α-quartz are reported. A qualitative explanation in terms of anharmonic deformation potential is given.
