摘要：

Numerical simulation based on first-principle calculations is applied to study the wurtzite AlxIn1-xN. Simulation results suggest that the Vegard's law deviation parameter is 0.063 +/- 0.014 angstrom for the a lattice constant, and -0.160 +/- 0.015 angstrom for the c lattice constant. The band gap bowing parameter is 3.668 +/- 0.147 eV with the lattice constants by means of the minimized equilibrium energy, and 3.457 +/- 0.152 eV with the lattice constants derived from Vegard's law.
