Yttrium nitride is hard ceramic material similar to titanium nitride and zirconium nitride. Under ambient conditions, rock salt phase of YN stablizes and its lattice constant is 4.88 Å.[1]
Yttrium nitride shows similar semiconducting properties as the nitrides of lanthanum, scandium. In its rock salt structure, YN exhibits an indirect bandgap in the range of 0.9-1.3 eV.[2]
Additionally the lattice structure of YN differs only by 8% from that of gallium nitride. This makes YN a possible buffer layer between a substrate and the GaN layer during GaN crystal growth.
