DESCRIPTION
Currently superconductors are used for Terahertz telescope detects but new graphene terahertz detectors will use less than 0.1% of the power. Instead of microwatts, the graphene detectors could use 0.1 nanowatts. If a superconducting detector could produce a single pixel then new graphene detectors could have 1000 to 10000 pixels. Above – The image depicts a schematic of terahertz (THz) heterodyne detection with graphene. In this, two THz waves (red) are coupled into graphene, where they are combined or mixed. One of the waves is a high intensity signal generated by a local THz light source (i.e. a local oscillator),
