Outline of Final Research Achievements

We focused on graphene with superior characteristics such as higher electron mobility, higher thermal conductivity and higher surface strength than copper, and studied the possibility of material for radio frequency cavity for particle accelerators. We attempted to fabricate radio frequency cavities of graphene by depositing graphene on the surface of oxygen free copper cavity by thermal CVD method. A thermal CVD furnace for forming a radio frequency cavity was fabricated and it was confirmed that graphene was formed on oxygen-free copper thin films. Then we tried to deposit graphene by the thermal CVD on an oxygen free copper cavity under the same conditions. Although some carbon film was deposited on the copper surface, the formation of graphene was not confirmed with Raman spectroscopy .
