InNxAs1-x band gap energy and band bowing coefficient calculation
Published online by Cambridge University Press: 13 December 2007
Abstract
The band gap energies of zinc-blende InNxAs1-x alloy as a function of its nitrogen composition have been calculated using the density functional theory. The results agree well with those obtained from experimental results. The minimum band gap energy of InNxAs1-x alloy obtained is 70 meV at its N composition of 0.45. The band gap bowing coefficient of InNxAs1-x alloy is obtained from the curve fitting of the simulated band gap energy versus the nitrogen composition, x. The band gap bowing coefficient of zinc-blende InNxAs1-x alloy is found to be 2.072 ± 0.236 eV. The energy band gap for InN is also correctly predicted from this calculation.
