Study on Heat Transfer Across Nanotip Contact Interface Under Near-Field Effect
Scanning probe lithography enables the processing of materials below 10 nm,bringing a new development direction for micro/nano processing technology.However,the heat transfer between the nanotip and the sample is a key factor affecting the temperature rise of the material and the processing effect.In this paper,a gold nanotip array-supported monolayer graphene structure is designed,and the thermal contact resistance between the tip and graphene is the main factor affecting the temperature rise of the structure under vacuum conditions.Firstly,the near-field enhancement factor of the gold nanopin-tip array under the 532 nm laser is evaluated to be about 3.2,and secondly,combined Raman experiments and simulation,the thermal contact resistance between the gold nanotip and graphene is determined to be～4.6×10-5(m2·K)/W.
