A self-powered and sensitive terahertz photodetection based on PdSe2
文献摘要：
With the rapid development of terahertz technology,terahertz detectors are expected to play a key role in diverse areas such as homeland security and imaging,materials diagnostics,biology,medical sciences,and communication.Whereas self-powered,rapid response,and room temperature terahertz photodetectors are confronted with huge challenges.Here,we report a novel rapid response and self-powered terahertz photothermoelectronic(PTE)photodetector based on a low-dimensional material:palladium selenide(PdSe2).An order of magnitude performance enhancement was observed in photodetection based on PdSe2/graphene heterojunction that resulted from the integration of graphene and enhanced the Seebeck effect.Under 0.1-THz and 0.3-THz irradiations,the device displays a stable and repeatable photoresponse at room temperature without bias.Furthermore,rapid rise(5.0 μs)and decay(5.4 μs)times are recorded under 0.1-THz irradiation.Our results demonstrate the promising prospect of the detector based on PdSe2 in terms of air-stable,suitable sensitivity and speed,which may have great application in terahertz detection.
