Abstract:
Effect of optical breakdown on second harmonic generation (SHG) from Si(111)7×7 was investigated. After the irradiation of a laser beam with a threshold energy for the optical breakdown, the intensity of second harmonics (SH) polarized along the [011̄] axis measured as a function of pump-polarization showed deviation from 90° periodicity which is expected from the surface C 3 v symmetry, although low energy electron diffraction (LEED) still exhibited the 7×7 structure. The irradiation of a more intense laser beam led to structural disorder, resulting in complete disappearance of SH periodicity, and no pattern of LEED was exhibited.
