Non-linear spin Seebeck effect due to spin-charge interaction in graphene
I. J. Vera-Marun, V. Ranjan, B. J. van Wees
The abilities to inject and detect spin carriers are fundamental for research on transport and manipulation of spin information. Pure electronic spin currents have been recently st…
Nonlinear interaction of spin and charge currents in graphene
I. J. Vera-Marun, V. Ranjan, B. J. van Wees
We describe a nonlinear interaction between charge currents and spin currents which arises from the energy dependence of the conductivity. This allows nonmagnetic contacts to be us…
Giant flexoelectric effect in two-dimensional boron-nitride sheets
Ivan Naumov, Alexander M. Bratkovsky, V. Ranjan
We find, with the use of first-principles calculations, that a single-atom-thick boron-nitride (BN) sheet exhibits an unusual nonlinear electromechanical effect: it becomes macrosc…
The Band Gap in Silicon Nanocrystallites
V. Ranjan, Manish Kapoor, Vijay A. Singh
The gap in semiconductor nanocrystallites has been extensively studied both theoretically and experimentally over the last two decades. We have compared a recent ``state-of-the-art…
