    • note
    • Under microscope light illumination, we lower the probe onto the Au pad while monitoring the current at zero bias with an electrometer and stop as soon as the current reading rises above the noise floor. This is photocurrent, which is larger than dark current. Hence, using photocurrent to determine electrical contact ensures minimal pressure exerted by the probe.

    • note
    • The light source was a tungsten halogen lamp through a grating monochromator (Jobin TRIAX 180) that was chopped at 250 Hz. The resulting photocurrent, measured between the Au and GaAs contacts of the sample at zero applied bias, was first amplified by a current preamp and then detected with a lock-in amplifier to reduce noise and dark current. The monochromator output was calibrated using silicon and germanium photodiodes, and the measured photocurrent spectra were normalized by the incident photon flux to give the photoresponse yield in Figure 4c.
