Enhancement of the spin Hall voltage in a reverse-biased planar p-n junction

We report an experimental demonstration of a local amplification of the spin Hall voltage using an expanding depletion zone at a p-n junction in GaAs/AlGaAs Hall-bar microdevices. It is demonstrated that the depletion zone can be spatially expanded by applying reverse bias by at least 10 μm at low t...
