Abstract
Atomic hydrogen irradiation leads to striking effects on the electronic properties of single quantum wells as measured by photoluminescence spectroscopy. The band-gap energy blueshifts with increasing hydrogen dose and finally saturates at the value of a corresponding reference sample without nitrogen. The luminescence intensity decreases upon hydrogen irradiation with a strong dependence on nitrogen content. The above results have been found in a large set of samples differing for nitrogen and indium content, and are related to the formation of bonds between hydrogen and one or more nitrogen atoms.
