Elastic constants of the II-IV nitride semiconductors MgSiN, MgGeN and MgSnN

Mikael Råsander, Michelle A. Moram

The single crystal elastic constants, polycrystalline elastic moduli and related properties of orthorhombic MgSiN, MgGeN and MgSnN have been calculated using dens…

On the thermal expansion in MgSiN

Mikael Råsander, Michelle A. Moram

The thermal expansion of the wide band gap semiconductor MgSiN has been determined using density functional calculations in combination with the quasi-harmonic approximation.…

Structure and lattice dynamics of the wide band gap semiconductors MgSiN and MgGeN

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 and MgGeN using density functional theory. In…

Electron effective mass and mobility limits in degenerate perovskite stannate BaSnO

Christian A. Niedermeier, Sneha Rhode, Keisuke Ide +4

The high room temperature mobility and the electron effective mass in BaSnO are investigated in depth by evaluation of the free carrier absorption observed in infrared spectra…

Electronic structure of the high and low pressure polymorphs of MgSiN

Mikael Råsander, Michelle A. Moram

We have performed density functional calculations on the group II-IV nitride MgSiN. At a pressure of about 20~GPa the ground state wurtzite derived MgSiN structure (LP-…
