Negative differential resistance in scanning tunneling microscopy: simulations on C${}_{60}$-based molecular overlayers

Frederico D. Novaes, Manuel Cobian, Alberto Garcia +3

We determine the conditions in which negative differential resistance (NDR) appears in the C${}_{60}$-based molecular device of [Phys. Rev. Lett. {\bf 100}, 036807 (2008)] by means o…
