Raman spectroscopy of graphene on different substrates and influence of defects
Anindya Das, Biswanath Chakraborty, A. K. Sood
We show the evolution of Raman spectra with number of graphene layers on different substrates, SiO/Si and conducting indium tin oxide (ITO) plate. The G mode peak position an…

Electrochemically Top Gated Graphene: Monitoring Dopants by Raman Scattering
A. Das, S. Pisana, S. Piscanec +8
We demonstrate electrochemical top gating of graphene by using a solid polymer electrolyte. This allows to reach much higher electron and hole doping than standard back gating. In-…
