The compounds exhibit piezoelectricity, which demands to break inversion symmetry, and then to be a semiconductor. For [Ga.sub.2][O.sub.3], the orthorhombic case ([epsilon]-[Ga.sub.2][O.sub.3]) of common five phases breaks inversion symmetry. Here, the piezoelectric tensor of [epsilon]-[Ga.sub.2][O....
