Graphene Transfer with Reduced Residue
arXiv:1301.4106 · doi:10.1016/j.physleta.2013.04.015
Abstract
We present a new transfer procedure for graphene using acetic acid, which removes the residue that is common in standard acetone treatments. Post-transfer samples cleaned with acetic acid and acetone were characterized using Raman spectroscopy and atomic force microscopy for comparison. We further illustrate the quality of our transfer process by using fluorescence quenching to create an optical map of surface contaminants.
