Abstract
The University of Central Florida invention is a spectrally selective infrared photodetector based on nanopatterned multilayer graphene intercalated with iron chloride (NPMLG-FeCl3). The design allows for wavelength tuning of the photodetection from ? =1.3 µm to 12 µm and beyond. This expansion in detection range improves on other graphene-based detector designs, as the short-wavelength infrared regime is out of range for nanopatterned monolayer graphene (NPG). Additionally, the device achieves increased absorption and ultrafast response time. These improvements in graphene-based photodetection enhance applications in optical IR communication, IR color displays and IR spectroscopy.
