Abstract 2D photodetectors operating in photovoltaic mode exhibit a trade‐off between response speed and photoresponsivity. This work presents phototransistor based on SnS 2 /ReSe heterojunction. Under negative bias, the energy band spike at heterojunction interface impedes carrier drifting so that dark current is as low 10 −13 A. The tunneling under positive bias significantly reduces transmission time of photogenerated carriers, which enhances responsivity specific detectivity to 32.77 A W...
