Red-Shift Effect and Sensitive Responsivity of MoS2/ZnO Flexible Photodetectors

摘要

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 10³ and 10⁴, respectively. The responsivity of MoS2/ZnO increased, and the wavelength was red-shifted.
