Description
Summary:Two-dimensional (2D) transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS 2 ) and tungsten diselenide (WSe 2 ), have recently attracted attention for their applicability as building blocks for fabricating advanced functional materials. In this study, a high quality hybrid material based on 2D TMD nanosheets and ZnO nanopatches was demonstrated. An organic promoter layer was employed for the large-scale growth of the TMD sheet, and atomic layer deposition (ALD) was utilized for the growth of ZnO nanopatches. Photodetectors based on 2D TMD nanosheets and ZnO nanopatches were successfully fabricated and investigated, which showed a high photoresponsivity of 2.7 A/W. Our novel approach is a promising and effective method for the fabrication of photodetectors with a new structure for application in TMD-based transparent and flexible optoelectronic devices. Two-dimensional transition metal dichalcogenides (TMDs) such as molybdenum disulfide, have recently attracted attention for their applicability as building blocks for fabricating advanced functional materials.
