Photo-excitation of electrons in metal was confirmed in the Au/Si Schottky barrier, and its excitation enhancement using surface plasmon was first observed in the wavelength range corresponding to less energy than the band-gap of silicon. The feasibility of new Schottky-type photodiodes, in which electrons are never generated by absorption in semiconductors but directly excited in metal, was experimentally demonstrated.
