The work is in the field of submillimeter wave detectors.  A                    multiple-layer metal/insulator device of the form MBMBMBM is prepared.          Because of the triple-barrier configuration, two metal layers are               isolated to form a dual quantum-well structure.  In theory, such                multiple-quantum-well, or resonant tunneling devices show prominent             region of negative resistance phenomena, and fall short in terms of             both the expected magnitude and definition of negative resistance               features.  To ameliorate this situation, efforts are underway to employ         state-of-the-art, thin-film deposition techniques to individually               prepare and obtain optimal characteristics of both metal and                    electron-barrier films; and to use superconducting test studies of              metal/barrier layers to assure the firmation of high quality electron           tunnel barriers.
