摘要: Numerical calculation based on first-principles is
applied to study the structural characteristics and the bandenergy
properties of wurtzite AlxGa1−xN. The lattice constants
obtained from the equilibrium energy are larger than those
obtained from the Vegard’s law. The deviation parameter is
0.040±0.005 °A for the a lattice constant and 0.125±0.009 °A
for the c lattice constant. The band gap energy is overestimated
with the Vegard’s law. The bowing parameter of direct (indirect)
band gap energy of 0.752±0.069 eV (0.889±0.057 eV)
is obtained with the equilibrium lattice constants, and 0.352± 0.046 eV (0.271±0.056 eV) is obtained with the lattice constants derived from the Vegard’s law.
