Calculation of the Piezoelectric Constants of α Quartz on Born's Theory

Abstract
The phenomenon of piezoelectricity in α quartz is related to the phenomena of infrared absorption and Raman scattering, using a model due to Kleinman and Spitzer. For right quartz the values computed for e11 and e14 are −0.052 C/m2 and 0.076 C/m2, respectively. (The values measured by Bechmann are −0.171 C/m2 and 0.0406 C/m2.) The calculation seems to be the first of its type to obtain the correct signs.
