In a recent study, researchers developed a novel graphene-enabled photodetector that operates at room temperature, is highly sensitive, fast, has a wide dynamic range, and covers a broad range of THz frequencies. The researchers have achieved a solid understanding of how the PTE effect gives rise to a THz-induced photoresponse, which is valuable for further detector optimization.
