In molecular physics, the van der Waals force is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; they are comparatively weak and therefore more susceptible to disturbance. The van der Waals force quickly vanishes at longer distances between interacting molecules. WebGraphite pieces were carefully examined, and a small piece of graphite was separated with possible large graphene sheets. A simple Scotch tape technique was used to transfer graphene from the selected graphite pieces onto a 300 nm SiO 2 coated Si (SiO 2 /Si) substrate for FET fabrication.
