ABSTRACT
The development of graphene by using low-cost and naturally available camphor as a carbon source has led to further expanding its reliability into various applications in energy conversion and storage devices. A homogenous island growth mechanism has been identified in the present work to achieve mono/bilayer graphene sheets using natural camphor by a very facile APCVD technique. The existence of the formation of graphene sheet has been determined by an intense 2D band at ~2700 cm–1 and G band at 1590 cm–1, respectively, for slow growth process at the rate of ~20 mg/min with 3.5 mg camphor kept at a constant camphor-to-substrate distance.
