Recently Demuth et al. [27.1] studied the temperature dependence of ultraviolet photoemission (UPS) and electron-energy-loss (EELS) spectra of Si(111)(7 × 7). Theyfound that significant temperature-dependent changes occur in occupied surface states and their transitions, thus suggesting important electron-phonon coupling at the surface.
