Dipolar molecules inside C70: an electric field-driven room-temperature single-molecule switch

Abstract

We propose a two-state electric field-driven room-temperature single-molecule switch based on a dipolar molecule enclosed inside ellipsoidal fullerene C₇₀. We show that the two low-energy minima of the molecular dipole inside the C₇₀ cage provide distinguishable molecular states of the system that can be switched by application of an external electric field.
