Self-Powered, Ultrathin, Flexible, and Scalable Ultraviolet Detector Utilizing a Diamond–MoS 2 Heterojunction

monolayer with an ultrathin, freestanding diamond membrane. The fabricated device operates at zero external bias and exhibits high responsivity and detectivity. Notably, mechanical bending enables strain-induced bandgap modulation of the diamond membrane, allowing dynamically tunable photoresponse─a capability absent in rigid diamond counterparts. To validate its practicality and scalability, a proof-of-concept UV imager was demonstrated. This newly developed configuration will undoubtedly open new routes toward scalable, integrable, and flexible UV sensing.
