The incorporation of hydrogen into strained InxGa1-xAs/GaAs quantum we
lls results in the formation of shallow, H-related radiative states wh
ich compete with, and quench, the intrinsic band-to-band luminescence.
By comparing the photoluminescence data obtained from hydrogenated ma
terial with secondary ion mass spectroscopy profiles from deuterated m
aterial, it is possible to deduce that the H-related radiative states
are associated with H which is accumulated at the well interfaces.
