Surface photovoltage and photoluminescence spectroscopy of self-assembled InAs/InP quantum wires

The optical properties of InAs/InP multi-layer quantum wire (QWR) structures of various spacer thicknesses have been investigated by means of room temperature surface photovoltage and photoluminescence spectroscopy. Combined with empirical tight binding calculations, the spectra have revealed transi...
