A versatile photodetector assisted by photovoltaic and bolometric effects

(Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS) A versatile photodetector based on MoTe2/VO2 heterostructure integrates photovoltaic and bolometric effects. The photodetector can realize three different functional modes including p-n junction, bolometer and Schottky junction, satisfying the demand of ultrasensitive and ultrabroad spectrum response, showing great potential in advanced photodetector.
