Abstract

We report on the temperature dependence of high-resolution angle-resolved photoemission spectra from d-like (Tamm) surface states on Cu₃Au(100) and Cu(100). The temperature was varied between T=39 and 600 K, the surface states were investigated in the vicinity of the M point of the corresponding surface Brillouin zones. On both samples, the temperature influences the Tamm states in a very similar way. We propose that d-like surface states may be used as sensitive probes to monitor the T-dependent potential changes in the outermost layer.
