  • Method of producing defect-free perfect surfaces
    Patent number: 5367980
    Abstract: A basic sample having a surface is set in an ultrahigh vacuum chamber. Atoms constituting the sample are deposited on the surface of the sample to remove vacancy-type defects. A laser beam having a predetermined wavelength and a predetermined fluence is radiated on the sample to remove adatom-type and kink-type defects, thereby producing a defect-free surface. In addition, the same material as that for a basic sample is deposited on a defect-free surface to produce a defect-free thin film.
