摘要
Large terraces of the Pt(111) surface are shown to reconstruct in the presence of a Pt gas-phase environment down to 400 K. The lifting of the reconstruction in the absence of the Pt gas phase is kinetically hindered up to 700 K. The main features of the reconstruction network as seen by the scanning tunneling microscope correspond to those inferred from x-ray scattering for the high-temperature (> 1330 K) spontaneous Pt(111) reconstruction. The parallel double corrugation lines forming the network have basically the same structure as those seen on the reconstructed Au(111) surface.
