研究目的
To synthesize and characterize heterojunction layers of graphene/MoS2 for optoelectronic applications.
研究成果
The synthesis approach successfully fabricates large-scale uniform MoS2 on graphene, as confirmed by AFM and Raman spectroscopy. The heterostructure shows promise for applications in wearable electronics.
研究不足
The study focuses on the synthesis and characterization of graphene/MoS2 heterostructures but does not explore their performance in specific optoelectronic devices.
1:Experimental Design and Method Selection:
The synthesis involves low pressure chemical vapor deposition (LPCVD) for graphene and atmospheric pressure CVD for MoS2 on graphene.
2:Sample Selection and Data Sources:
Copper foil is used as a substrate for graphene synthesis. MoO3 powder and sulfur powder are used for MoS2 synthesis.
3:List of Experimental Equipment and Materials:
Equipment includes LPCVD setup, AFM (NT-MDT), SEM (JEOL - JAPAN JSM 6390A). Materials include MoO3 powder, sulfur powder, copper foil, acetylene, hydrogen gas, argon gas.
4:Experimental Procedures and Operational Workflow:
Graphene is synthesized on copper foil using LPCVD. MoS2 is then synthesized on graphene using atmospheric pressure CVD.
5:Data Analysis Methods:
Characterization techniques include AFM, SEM, and Raman spectroscopy to analyze the thickness uniformity and structural properties of the heterostructure.
