Electron-beam assisted selective growth of graphenic carbon thin films on SiO2/Si and quartz substrates
arXiv:1512.07369
Abstract
The first selective growth of graphenic carbon thin films on silicon dioxide is reported. A preliminary e-beam exposure of the substrate is found to strongly affect the process of such films growth. The emphasis is placed on the influence of substrate exposure on the rate of carbon deposition. The explanation of this effect is proposed. The data of electrical and optical measurements and the results of atomic force and scanning electron microscopy and Raman spectroscopy studies are reported. The results suggest that the selective growth of graphenic carbon thin films on an irradiated SiO2/Si substrate is a promising approach to producing a microstructure at the pre-synthesis step without full lithography process.
