The extended growth of graphene oxide flakes using ethanol CVD
We report the extended growth of Graphene Oxide (GO) flakes using atmospheric pressure ethanol Chemical Vapor Deposition (CVD).
GO was used to catalyze the deposition of carbon on substrate in the ethanol CVD with Ar and H2 as carrier gases. Raman, SEM, XPS
10 and AFM characterized the growth to be reduced GO (RGO) of <5 layers. This new grown RGO possesses lower defect density with
larger and increased distribution of sp2 domains than chemically-reduced RGO. Furthermore this method without optimization reduces
relative standard deviation of electrical conductivity between chips, from 80.5% to 16.5%, enabling RGO to be used in practical
electronic devices
