摘要：

Temperature dependence of the second harmonic generation of the Si(111)-7 x 7 surface was measure in the temperature range from 550-degrees-C to 1100-degrees-C. For the first time Si(111)-7 X 7 <-> 1 x 1 phase transition around 860-degrees-C was observed as an abrupt intensity change of the SH signal within 15 degrees using an optical technique. A hysteretic behavior with temperature difference of 2-degrees-C was observed in heating and cooling processes over the transition region. A gradual decrease of the SH intensity with temperature was also observed.
