Colorized scanning electron microscope image schematically depicting the device with the experimental setup. An energy-tunable hard X-ray beam was focused onto the GaAs nanowire with a p–n junction along the growth axis and a diameter of 150 nm. The nanowire was contacted, which allowed for in-operando X-ray beam induced current (XBIC, see inset), X-ray fluorescence (XRF), and X-ray absorption near-edge spectroscopy (XANES) measurements while applying external voltages.
