EN

An asymmetric n-i-n like-II GaAs/GaAlAs/AlAs quantum heterostructure was designed and fabricated in order to observe a static photovoltage with a spectrally dependent sign. This photovoltage is associated with a light induced spatial separation of electrons and holes within selected regions of the structure. The observed photovoltage spectrum is compared with luminescence and luminescence excitation results.
