Abstract:
Two-dimensional (2D) van der Waals heterojunction offers alternative facile platforms for many optoelectronic devices due to no-dangling bonds and steep interface carrier gradient. Here, we demonstrate a 2D heterojunction device, which combines the benefits of high carrier mobility of 2D MoTe2and strong light absorption of perovskite, to achieve excellent responsivity. This device architecture is constructed based on the charge carriers separation and transfer with the high-gain photogating effect at the interface of the heterojunction. The device exhibits high responsivity of 334.6 A W-1, impressive detectivity of 6.2 × 1010Jones. All the results provide the insight into the benefits of interfacial carriers transfer for designing hybrid perovskite-2D materials based optoelectronic devices.
