Nanocrystal protective layer for crossbar molecular electronic devices

An array of molecular devices forming a crossbar, said molecular devices each comprising a junction formed by a pair of crossed electrodes where a first electrode is crossed by a second electrode at a non-zero angle and at least one connector species comprises at least one switchable moiety and functional ligands at each end of said connector species, said at least one connector species electrically connecting said pair of crossed electrodes in said junction, said junction having a functional dimension in nanometers, said molecular device further including a buffer layer interposed between said connector species and said second electrode.

A method of fabricating a molecular device comprising a junction formed by a pair of crossed electrodes where a first electrode is crossed by a second electrode at a non-zero angle and at least one connector species comprises at least one switchable moiety and functional ligands at each end of said connector species, said at least one connector species electrically connecting said pair of crossed electrode in said junction, said junction having a functional dimension in nanometers, said method including forming a buffer layer comprising nanocrystals with said connector species on said first electrode and forming said second electrode on said buffer layer.
