Tunable Superlattice in Graphene To Control the Number of Dirac Points
Sudipta Dubey, Vibhor Singh, Ajay K. Bhat +6
Superlattice in graphene generates extra Dirac points in the band structure and their number depends on the superlattice potential strength. Here, we have created a lateral superla…

Dual top gated graphene transistor in the quantum Hall regime
Ajay K. Bhat, Vibhor Singh, Sunil Patil +1
We study the effect of local modulation of charge density and carrier type in graphene field effect transistors using a double top gate geometry. The two top gates lead to the form…

Field-effect modulation of conductance in VO2 nanobeam transistors with HfO2 as the gate dielectric
Shamashis Sengupta, Kevin Wang, Kai Liu +4
We study field-effect transistors realized from VO2 nanobeams with HfO2 as the gate dielectric. When heated up from low to high temperatures, VO2 undergoes an insulator-to-metal tr…
