Density-functional calculations are used to clarify the role of an ultrathinLiF layer on Al electrodes used in molecular electronics. The LiF layer createsa sharp density of states (DOS), as in a scanning-tunneling microscope (STM)tip. The sharp DOS, coupled with the DOS of the molecule leads to negativedifferential resistance (NDR). Electron transfer between oriented moleculesoccurs via resonant tunneling. The I-V characteristic for a thin-film of tris(8-hydroxyquinoline)- aluminum (AlQ) molecules, oriented using electric-fieldpoling, and sandwiched between two Al/LiF electrodes is in excellent agreementwith theory. This molecular device presents a new paradigm for a convenient,robust, inexpensive alternative to STM or mechanical break-junction structures.Comment: 5 pages, 3 figure
