The Effect of Pressure on Band Parameters and Optical Characteristics in Indium Nitride.

The effect of pressure on band parameters and optical characteristics in the zinc-blende structure of InN has been investigated. An ab initio pseudopotential plane waves method has been used. At zero pressure, our results regarding the fundamental energy band gap, electron effective mass and many optical parameters concord well with recent experimental data. Monotonic and non-linear behavior of most quantities have been shown upon compression. The present study is useful for the use of zinc-blende InN in optoelectronics and microelectronics applications.
