Patent

CA 2404832

Molecular scale electronic devices (1) are disclosed. Such devices include at least two conductive contacts (9 and 11), and a conductive path (13) bridging the contacts. The conductive path is able to be written into a perturbed state by a voltage pulse, which can be of high or low conductivity, relative to an initial state. The conductive path comprises organic molecules including at least one electron-withdrawing group. Room temperature negative differential resistance is exhibited by the devices.

L'invention porte sur des dispositifs électroniques à l'échelle moléculaire comprenant au moins deux contacts conducteurs et un chemin conducteur enjambant les contacts. Le chemin conducteur peut être figé à l'état perturbé par une impulsion en tension correspondant à niveau de conductivité élevé ou faible par rapport à un état initial. Le chemin conducteur comprend des molécules organiques comprenant au moins un groupe suppresseur d'électrons. Ces dispositifs font preuve d'une résistance différentielle négative à température ambiante.
