The Si<Subscript>3</Subscript>N<Subscript>4</Subscript> and Ge<Subscript>3</Subscript>N<Subscript>4</Subscript> are important structural ceramics with many applications because of their attractive high temperature and oxidation resistant properties. The high-pressure and high-temperature spinel phases of these two materials were noticed to have wide, direct electronic band gaps. Other...</subscript></subscript></subscript></subscript>
