title: Red-Shift Effect and Sensitive Responsivity of MoS2/ZnO Flexible Photodetectors.
abstract: The optoelectronic characteristics of molybdenum disulfide (MoS2)/ZnO flexible photodetectors are investigated. A red-shift effect and improved photocurrent properties of the flexible devices are demonstrated. MoS2 doping improved the photocurrent properties and conductivity. The photocurrent/dark current ratios of pure ZnO and MoS2/ZnO flexible photodetectors were 10(3) and 10(4), respectively. The responsivity of MoS2/ZnO increased, and the wavelength was red-shifted.
