Dipolar molecules inside C-70: an electric field-driven room-temperature single-molecule switch

摘要

We propose a two-state electric field-driven room-temperature single-molecule switch based on a dipolar molecule enclosed inside ellipsoidal fullerene C-70. We show that the two low-energy minima of the molecular dipole inside the C-70 cage provide distinguishable molecular states of the system that can be switched by application of an external electric field.
