Abstract

We report on the epitaxial growth and photoluminescence (PL) of InAs0.926Sb0.063N0.011/InAs multi-quantum wells (QWs) grown using plasma-assisted molecular beam epitaxy. These dilute nitride QWs exhibit bright PL in the mid-infrared spectral range up to a temperature of 250 K without any post-growth annealing. Consideration of the power dependent PL behaviour is consistent with a type I band line-up in these QWs, arising from a strong lowering of the conduction band edge due to N-induced band anti-crossing effects.
