Characteristics of the PtSe2/graphene low-energy photon detector.

Caption

a, Schematic diagram of the device architecture. Inset: the optical micrograph of the device. b, Comparisons of NEP at 0.3 THz among pristine metal-PtSe2-metal, asymmetric nanogap slit device, and PtSe2-graphene vdW heterostructure. c, The optical picture of a fresh leaf and a metallic ring used in the imaging and 0.3 THz transmissions nondestructive image of the fresh leaf demonstrates the leaf vein, which partly contains more moisture.
