ORGANIC FILM TUNNELING EFFECTS AND DEVICES.
Abstract
Approximately 400 individual metal-organic-metal junctions were prepared using the Langmuir film techniques. Of these, 360 were electrically tested to obtain current-voltage characteristics, the remainder being used for wetting experiments or lost in processing. Au, Ag, Cu, and Sn were used for the electrode materials with from one to ten layers (25 to 250 angstroms) of calcium stearate, barium stearate, stearic acid, or polyvinylbenzoate (PVB) as the organic film. Major emphasis was placed on the study of process uniformity and the determination of the gross variations in electrical behavior with film thickness, choice of electrode metals, and processing techniques. IR absorption studies were conducted on bulk samples of PVB and stearic acid before and after irradiation by a Cs-137 gamma source and 2 Mev electrons from a Van de Graff accelerator, in order to estimate the structural alterations which can be induced in monolayer samples. Preliminary results with PVB were encouraging. (Author)
