Structure and lattice dynamics of the wide band gap semiconductors MgSiN${}_2$ and MgGeN${}_2$

M. Råsander, J. B. Quirk, T. Wang +4

We have determined the structural and lattice dynamical properties of the orthorhombic, wide band gap semiconductors MgSiN${}_2$ and MgGeN${}_2$ using density functional theory. In…
