Quantum Hall effect in graphene transferred by water-soluble transfer sheet and home-use laminator

Abstract

For electronic device applications, large-area graphene grown on a metal catalyst by chemical vapor deposition
requires a transfer to an insulating substrate. Previously, a transfer method that uses water-soluble
polyvinyl alcohol and a laminator was proposed. The method is simple, harmless, and does not require advanced
facilities. Based on this method, we fabricated fine patterns on graphene transferred onto a SiO2/Si
substrate using lithography and investigated their transport properties. The carrier is controlled between the
electrons and holes. The quantum Hall effect is observed at low temperatures. This method can be an option
for graphene device production.
