“…This intermediate phase, however, was not observed by Ne atom diffraction [60], surface x-ray diffraction [36,40] or LEED [62,63]. The origin of the discrepancy has been discussed by several authors [12,38,51,60,[64][65][66]. In particular, Ernst et al [51] suggested that an incommensurate CDW phase is actually realized in the intermediate temperature range while at the same time the amplitude of the associated PLD is smaller than the detection limit of the x-ray diffraction (∼0.05 Å) [36].…”

Studies of the Peierls-type charge-density-wave (CDW) transitions on metal surfaces are reviewed. After the background is reviewed based on the theoretical and experimental works on such transitions in bulk quasi-low-dimensional materials, two prototypical examples are presented. One is the well known surface reconstruction transition on W(001) and Mo(001), for which there was a long-standing controversy whether the transition is due to the CDW formation or the local bonding. It is emphasized that these two pictures do not contradict each other but describe the equivocal nature of this phenomenon. The second example is the phase transition in ultrathin In films on Cu(001), which is governed by the nesting of the Fermi surface constituted by a nearly-freeelectron-like sp surface resonance band, in contrast with the case of W and Mo, where much-localized d-band surface resonances play a dominant role. Finally, the origin of the long-periodicity structures widely observed in sp metals on fcc(001) systems is discussed in terms of the Fermi-surface topology expected to be common in these systems, which would be driven by strong electronphonon coupling to lead these surfaces to the formation of the peculiar long periodicities.
