Although alpha-phase tellurium dioxide (paratellurite, alpha-TeO2) is one of the few materials belonging to this symmetry class, this material has been primarily studied for its interesting optical properties.
Introduction The study and understanding of different piezoelectric materials over the last century contributed to the development of many important applications, such as MEMS or microphones.
However, although there exist 20 piezoelectric crystal classes, these various modes occur simultaneously and are typically interdependent and electromechanically coupled; very few materials offer a pure face-shear mode; although β-quartz allows this mode in certain orientations [1], it is thermodynamically stable only at high temperatures.
