Semiconducting II-IV nitrides exhibit tunability of optoelectronic properties similar to that the group III nitrides, while comprising earth-abundant and potentially low-cost elements. However, synthesis is immature, limiting explorations. Herein, ZnSnN2 hetero-epitaxial films grown by high-power impulse magnetron sputtering, having quality at level III-nitrides layers without dislocation-reduc...
