Responsivity and on-chip device density of different plasmon-enhanced and non-plasmonic photovoltage detection methods. The plasmon-enhanced photodetectors include Si nanoribbon at high(top) and low(bottom) optical power62, Si pyramids63, Au nanoparticles (AuNP) on graphene (Gr)64, planar metal–oxide–metal (Au-Al2O3-Au) tunnel junction)65, Thermocouple (TC) antenna)66, Topological insulators (TI)67, and polycrystalline Au plasmonic nanogaps52. The non-plasmonic photodetectors include transition metal dichalcogenide WSe268 and MoS269, black phosphorus (BP)70, supported71 and suspended graphene72, InAs/InP nanowire73, suspended carbon nanotubes (CNT)74, bi-metal nanowire thermocouple (Bi-metal)75, single metal (NiTC) nanostructure76, ZnSe–ZnO nanowire axial p–n junctions77 and ZnO/GaN nanoscale p-n junctions78
