“…However, the size of the gap observed in the 3 ͱ 2 low-temperature phase turned out to be at least 45 times larger than the value predicted for weak CDWs. 9,12 These features have also been reported for the phase transitions found in the In/Cu͑100͒ and Pb/Cu͑100͒ systems 8,10,16 and are typical of the new paradigm.…”

“…Metal monolayers deposited on Cu͑100͒ have deserved ample attention during recent years as model systems to understand surface CDWs. [6][7][8][9][10][11][12][13] A CDW is a charge-ordered state with very interesting properties because it represents an accessible macroscopically coherent state. 14,15 In the CDW state, the lattice reorders slightly at expenses of the elastic energy, giving rise to a periodic lattice distortion and a new supercell.…”

The surface phase transition and low-temperature phase of α-Ga(0 1 0) studied by SPA-LEED

“…Anti-phase domains have been observed in many surface structures (for recent examples see Refs. [11,12]). The structure observed here, however, is remarkable in two ways.…”

Surface dynamics on submonolayer Pb/Cu(001) surfaces

“…Indeed, the formation of the domain boundaries is a way to compress the c (2 × 2) structure. In contrast to the well studied film growth mechanism and electronic structure of Pb/Cu(001) systems, 14,21,22 a detailed description of their dynamics is absent up until today.…”
