Abstract

Gated graphene has been used to realize a microwave power detector. A Corbino disc structure with Ti/Ag contacts has been fabricated on top of graphene deposited on P-type Si substrates with SiO2 gate oxides. This device exhibits power detection with a sensitivity reaching 0.87 mV/mW at a frequency of 433.92 MHz using lock-in detection at room temperature.
