And the ratio I G/I 2D shows that the number of graphene Screening Library supplier layers cannot be controlled by implantation dosage purely but are associated with carbon atoms precipitation and segregation from inside to the surface grain boundaries of the substrate during
thermal treatment. From ultra-thin carbon film to graphene by means of the similar cluster ion implantation technique, it is conductive for cluster implantation of light elements to develop low-energy shallow ion implantation in semiconductor industry.
