High-speed hBN/graphene/hBN room-temperature terahertz nano-receivers
2021
We report room temperature terahertz detection in hBN/graphene/hBN heterostructures. The obtained record combination of high-speed (response time < 1 ns) and high sensitivity (noise equivalent power ~ 100 pWHz-1/2) is enabled by the photo-thermoelectric effect.
