Outline of Final Research Achievements

In this work, comprehensive materials research was carried out for future electronic devices. Our target material is a so called superlattice structure consisting of two different chalcogenide compounds. It was found by theoretical simulation that electronic characteristics strongly depended on the choice of the compound. The physical properties of a proposed superlattice were also evaluated experimentally. Even though material fabrication is still developing, further improvements will be expected to realize a such new functional electronic device.
