Organic rubrene/topological insulator Bi₂Se₃/SiO₂ hybrid heterojunction photodetectors for broadband and ultrafast photodetection application

Novel photodetectors have been developed by using the organic/inorganic hybrid heterostructure of the rubrene/topological insulator Bi2Se3, which demonstrate superior photodetection performance benefiting from the Dirac surface state at the heterointerface.
