Formation of p-n junction in polymer electrolyte-top gated bilayer graphene transistor
Biswanath Chakraborty, Anindya Das, A. K. Sood
We show simultaneous p and n type carrier injection in bilayer graphene channel by varying the longitudinal bias across the channel and the top gate voltage. The top gate is applie…

Probing the doping in metallic and semiconducting carbon nanotubes by Raman and transport measurements
Anindya Das, A. K. Sood, A. Govindaraj +4
In-situ Raman experiments together with transport measurements have been carried out on carbon nanotubes as a function of gate voltage. In metallic tubes, a large increase in the R…
