Abstract

We report the structural, electrical and optical properties of bulk InAsN alloy with various nitrogen contents deposited on (100) InP substrates by using plasma-assisted gas source molecular beam epitaxy. It is found that the fundamental absorption edge of InAsN, as compared to that of InAs, shifts to higher energy due to Burstein-Moss effect. A dramatic increase of the electron effective mass in a nitrogen-containing III-V alloy is also observed from infrared reflectivity and Hall measurement on these degenerate InAsN samples. The sizeable increase on electron effective mass is consistent with the theoretical predictions based on band-anticrossing model.
