Controlled synthesis of single-crystalline graphene

Blog Article

This paper reports the controlled synthesis of single-crystalline graphene on Hand Sanitizers the back side of copper foil using CH4 as the precursor.The influence of growth time and the pressure ratio of CH4/H2 on the structure of graphene are examined.An optimized polymer-assisted method is used to transfer the synthesized graphene onto a SiO2/Si substrate.

Scanning electron microscopy and Raman spectroscopy are used to Bariatric Beds characterize the graphene.
