The high pressure and temperature reaction was responsible for the formation of stoichiometric ZnSiP2 and ZnGeP2 with zinc-blende and chalcopyrite structures. The optical and electrical properties of these compounds were examined and discussed on the basis of a quasicubic model. New periodic compounds, ZnSiN2 and ZnGeN2 were prepared under conditions of 4.0 to 7.7 GPa and 800 to 1500°C.
Both of them were identified as distorted wurtzite type structure. Solid solution, ZnSil-xGexN2 was also obtained with a volume change of the orthorombic unit cell corresponding to the discrepancy of atomic radii. The optical band gap has a tendency to shift linearly from 5.23 eV to 3.45 eV with increasing the value of x.
