Determining the Mechanism of Low Temperature Graphene Growth

Abstract

A single layer graphene electrode has been successfully grown by the chemical vapour deposition (CVD) method using a liquid chlorobenzene carbon source trapped in a PMMA polymer matrix at a growth temperature of 450 deg C. Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and Ultraviolet-Visible (UV-vis) absorption spectroscopy have been used to identify the graphene based composition. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) have been used to characterize the film quality and growth dynamics. SEM snapshots show a preferential edge growth mechanism of single layer graphene has been observed as a function of growth time with distinct domains where only the edges parallel to the growth front are active to accept incoming carbon source. This work paves a potential pathway for an easier and cheaper production of large area conductive and transparent electrodes.
