Mono‐ and Bilayer MoS2 Photodetectors: High‐Performance Broadband AC Readout With Color‐Selective Noise Suppression

Advanced Optical Materials, EarlyView.
Mono‐ and bilayer MoS2 photodetectors enable wavelength‐selective AC photoresponse and optically driven capacitance modulation under visible illumination. Green excitation produces the strongest cumulative capacitive response, consistent with trap‐mediated charge accumulation at mono/bilayer and metal–MoS2 interfaces.
