Raman Spectroscopy and Electrical Characterisation of Reactive Ion Etched Multilayer Graphene
Raman Spectroscopy and Electrical Characterisation of Reactive Ion Etched Multilayer Graphene
A reactive ion etching process (RIE) of multi-layer graphene (MLG) has been developed to obtain tri-layer (TLG) or bi-layer graphene (BLG). A controllable graphene etch rate of 0.19 nm/sec has been achieved by using oxygen plasma. Graphene D, G and 2D band characteristics have been obtained by Raman spectroscopy and rapid thermal annealing (RTA) has shown to reduce defect band in etched graphene layer. A two terminals device with etched tri-layer graphene and back gate has been fabricated. Measurement shows drain current variation with gate voltage bias and mobility of 52 cm2/V-s has been achieved.

Abstract
A reactive ion etching process (RIE) of multi-layer graphene (MLG) has been developed to obtain tri-layer (TLG) or bi-layer graphene (BLG). A controllable graphene etch rate of 0.19 nm/sec has been achieved by using oxygen plasma. Graphene D, G and 2D band characteristics have been obtained by Raman spectroscopy and rapid thermal annealing (RTA) has shown to reduce defect band in etched graphene layer. A two terminals device with etched tri-layer graphene and back gate has been fabricated. Measurement shows drain current variation with gate voltage bias and mobility of 52 cm2/V-s has been achieved.
