• Temperature dependence of the second harmonic generation of the Si(111)-7×7 surface was measured in the temperature range from 550℃ to 1100℃. For the first time Si(111)-7×7&↔1×1 phase transition around 860℃ 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℃ was observed in heating and cooling processes over the transition region. A gradual decrease of the SH intensity with temperature was also observed.
