Scandium nitride (ScN) is a binary III-V indirect bandgap semiconductor. It is composed of the scandium cation and the nitride anion. It forms crystals that can be grown on tungsten foil through sublimation and recondensation.[1] It has a rock-salt crystal structure with lattice constant of 0.451 nanometer, an indirect bandgap of 0.9 eV and direct bandgap of 2 to 2.4 eV.[1][2] These crystals can be synthesized by dissolving nitrogen gas with indium-scandium melts, magnetron sputtering, MBE, HVPE and other deposition methods.[2][3] Scandium Nitride is also an effective gate for semiconductors on a silicon dioxide (SiO2) or hafnium dioxide (HfO2) substrate.[4]
