Pulsed Near-IR Photoresponse in a Bi-metal Contacted Graphene Photodetector
We use an ultra-fast near-infrared pulse coincidence technique to study the time, temperature, and power dependence of the photoresponse of a bi-metal contacted graphene photodetector. We observe two components of the photovoltage signal. One component is gate-voltage dependent, linear in power at r...
