Strong enhancement of piezoelectric constants in ScxAl1−xN: First-principles calculations
AIP Advances, 2016 We theoretically investigate the piezoelectricity of ScxAl1−xN in the entire range of x by first-principles calculations. We find that the piezoelectric constants of wurtzite-type ScxAl1−xN significantly enhance as x increases from 0 to 0.75.
