| Outline of Final Research Achievements |
Metal-semiconductor-metal (MSM) structures, hetero pn junctions, and homo pn junctions comprising ultrananocrystalline diamond films were prepared. For the MSM structures, it was found that Cu electrodes can suppress the dark current and its employment makes possible clear photodetection in the MSM structure, and their photo-responses in the ultraviolet and visible range might be attributed to photo-carriers generated in nanodiamond grains and grain boundaries. In addition, the Schottky barrier height was estimated from ultraviolet and X-ray photoemission spectra measured with synchrotron radiation, and it was proved that Schottky/ohmic contacts are flexibly formed by selecting metallic materials.
