First-principles calculations are performed to compute the e<Subscript>33</Subscript> piezoelectric coefficients of GaN, ScN and (Sc<Subscript>x</Subscript>Ga<Subscript>1-x</Subscript>N) alloys exhibiting an alternation of hexagonal GaN, with hexagonal ScN along the c-axis. For Sc compositions larger than 50%, each atom has nearly five nearest neighbors (i.e.,...</subscript></subscript></subscript>
