Simultaneous optical-electrical operation of mixed-mode cross-bar devices. The dimension of the device under test is 1 × 1 µm2 in size. (a) Duration and power of laser pulses applied to the cross-bar device during the mixed-mode switching experiments. (b) Real time monitoring of device resistance, showing controllable switching between high and low state when appropriate excitation is being applied. Sensing voltage equal 0.1 V was applied. (c) Time resolved measurement of the cross-bar device under a single laser pulse. The device was biased at 0.5 V and the current started out at 43 µA and ended up at 32 µA, indicating an increase of resistance and manifests a partial RESET process.
