Abstract

Here, an approach for synthesizing large-Area and high-quality MoS2 flakes was developed. In addition, we made up the MoS2 photoelectric detector and studied the photocurrent response of the detector. We firstly used the ceramic pieces to control MoO3 evaporation for obtaining large-Area MoS2. Our CVD reaction is hydrogen free, very simple operation, high repetition rate and cost saving. The obtained MoS2 flakes exhibited large-Area with lengths up to 400-500 micrometers. Through analyzing optical microscopy(OM), Raman and atomic force microscopy(AFM), we confirm the MoS2 thin film is bilayer. And the photoelectric characteristic experiment shows that the photoelectric detector has sensitive photoelectric response with the fine stability.
