摘要
A first-principle molecular dynamics calculation of structural and lattice dynamic properties of wurtzite GaN and InN was presented. The simplest partial ionic two-body potential model was employed to reproduce the lattice constants and the phonon frequencies of InN and GaN. From the temperature dependence of the lattice constant and the vibration amplitudes it was made clear that lattice instability existed in InN induced by the vibration of the atoms along the c-direction.
