Wavelength-Tunable IR Detector based on Suspended Bilayer Graphene Micro Ribbons

Abstract

The original goal of this three-year project was to investigate bandgap-tunable bilayer-graphene microribbons allowing continuously tunable photodetection in the IR bands. Due to the government sequestration, the 2nd and 3rd years increments toward this project have been defunded. Here we are using our 1st year result as our final performance report. To this end we designed, fabricated, and characterized in Year One a device with suspended graphene microribbons, and found that fully suspended CVD-grown graphene devices are dominated by the photoelectric effect, which is promising towards CVD-grown graphene photodetectors approaching THz cut-off frequencies.
