High Gain and Broadband Absorption Graphene Photodetector Decorated with Bi(2)Te(3) Nanowires

A graphene photodetector decorated with Bi(2)Te(3) nanowires (NWs) with a high gain of up to 3 × 10(4) and wide bandwidth window (400–2200 nm) has been demonstrated. The photoconductive gain was improved by two orders of magnitude compared to the gain of a photodetector using a graphene/Bi(2)Te(3) n...

description A graphene photodetector decorated with Bi(2)Te(3) nanowires (NWs) with a high gain of up to 3 × 10(4) and wide bandwidth window (400–2200 nm) has been demonstrated. The photoconductive gain was improved by two orders of magnitude compared to the gain of a photodetector using a graphene/Bi(2)Te(3) nanoplate junction. Additionally, the position of photocurrent generation was investigated at the graphene/Bi(2)Te(3) NWs junction. Eventually, with low bandgap Bi(2)Te(3) NWs and a graphene junction, the photoresponsivity improved by 200% at 2200 nm (~0.09 mA/W).
