THz radiation can be detected by graphene FETs fabricated on a flexible polymer substrate, according to Chalmers University in Sweden. At room temperature, it detects signals from 330 to 500GHz. According to “A flexible graphene terahertz detector” in Applied Physics Letters, estimated noise equivalent power in the antenna-coupled graphene FETs at room temperature is below 3nW/√Hz at ...
