Ga Kα X-ray fluorescence (XRF; left) and X-ray beam induced current (XBIC; right) maps of the p–n junction taken as a function of applied voltage and excitation X-ray energy. The GaAs nanowire (as located in the Ga map) is indicated by the dashed, black and white lines, respectively. The Roman numbers indicate the measurement sequence and XRF counts and XBIC currents are scaled equally on a logarithmic scale for all voltages and energies, respectively. The spatial scale bar is 300 nm.
