摘要：

Atomic hydrogen irradiation leads to striking effects on the electronic properties of InxGa1-xAs1-yNy/GaAs single quantum wells as measured by photoluminescence spectroscopy. The InxGa1-xAs1-yNy 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.
