| dc.description.abstract | The electronic structure of Pb/Ge(111) has been probed along the temperature-induced phase transition ct -root 3X root 3R30 degrees double right arrow 3 X 3 using angle-resolved photoemission. The alpha-root 3X root 3R30 degrees phase is metallic due to the existence of a half-filled, dispersing surface band. The 3 X 3 phase is characterized by the appearance of an additional surface band with 3 X 3 periodicity, whose role in the phase transition is discussed. The Fermi-surface topology of the alpha-root 3X root 3R30 degrees phase has been probed using angle-resolved photoemission. Its shape is undulated, and it resembles strongly the theoretical prediction, with a Fermi momentum of 0.31 Angstrom(-1) along <(Gamma K)over bar> directions and 0.40 Angstrom(-1) along <(Gamma M)over bar> directions. These values were determined from different experimental methods, and agree with the values needed for a perfect 3 X 3 nesting. However, the Fermi surface exhibits no large flat areas suitable for electronic nesting. | |

The origin of this feature lies in the enhanced intensity detected at~0.2 eV BE at T_11 , which is probably related with the other phenomenafound in this area at LT (see Sec. IV). 38. The intensity enhancement in the two bottom corners of Fig. 6 (top) comes from a larger bulk band-gap projection and matrix element effects in the second Brillouin zone (Ref. 23). 39. G. H. Gweon, J.
