Graphene analogue BCN: femtosecond nonlinear optical susceptibility and hot carrier dynamics
Sunil Kumar, N. Kamaraju, K. S. Vasu +3
Third-order nonlinear absorption and refraction coefficients of a few-layer boron carbon nitride (BCN) and reduced graphene oxide (RGO) suspensions have been measured at 3.2 eV in…
Probing top-gated field effect transistor of reduced graphene oxide monolayer made by dielectrophoresis
K. S. Vasu, Biswanath Chakraborty, S. Sampath +1
We demonstrate top-gated field effect transistor made of reduced graphene oxide (RGO) monolayer (graphene) by dielectrophoresis. Raman spectrum of RGO flakes of typical size of 5μm…
Femtosecond Photoexcited Carrier Dynamics in Reduced Graphene Oxide Suspensions and Films
Sunil Kumar, N. Kamaraju, K. S. Vasu +1
We report ultrafast response of femtosecond photoexcited carriers in single layer reduced graphene oxide flakes suspended in water as well as few layer thick film deposited on indi…
