Si 2p core-level photoemission spectra of Si(111) have been recorded as a function of temperature from 300 up to 1673 K. With increasing temperature a strong shift in binding energy and thermal broadening have been observed. Apart from the (7 × 7)-(1 × 1) phase transition at 1150 K the temperature evolution of the spectral centroid gives evidence for a high temperature phase transition at 1550 K.
