Abstract
Single-molecule devices can reach the physical limits of miniaturization and data storage density. Employing first-principles calculations and the non-equilibrium Green’s function method, we investigate Sn-phthalocyanine (SnPc) on an in-plane hBN-graphene heterostructure. The Sn atom can protrude to both sides of Pc (away from and toward the in-plane hBN-graphene heterostructure) and transformation between these two states is possible by means of the tip of a scanning tunneling microscope. We find that the difference in conductance between the two states provides an excellent switching ratio, which can be further enhanced by application of an in-plane bias and by gating.
