Abstract

We present tight-binding band-structure calculations for InN_xAs_{1 - x} alloys as a function of the nitrogen concentration. The high-concentration regime is found to be extremely sensitive to x. The low-concentration region (0 < x < 0.25) is of technological interest and is examined in detail. Effects of clustering, percolation, and the dependence of the energy gap on the assumed valence-band offsets on the band gap are reported.
