Broadband, Polarization-Sensitive, and Self-Powered High-Performance Photodetection of Hetero-Integrated MoS₂ on Lithium Niobate.

ABSTRACT: High-performance photodetectors hold promising potential in optical communication and imaging systems. However, conventional counterparts are suffering narrow detection range, high power consumption, and poor polarization sensitivity. Characteristics originating from switchable polarization in ferroelectrics can be used to optimize the photo-to-electric procedure and improve the photodetection performance. In this regard, we constructed a configuration by integrating 2-dimensional molybdenum disulfide (MoS₂) with ferroelectric lithium niobate (LiNbO₃), resulting in the MoS₂/LiNbO₃ heterostructured photodetector. Benefiting from the pyroelectric effect of LiNbO₃, the limitation of bandgap on the detection range can be broken, thus broad
