Experimental Fermi surface of Mo(011)

Abstract: High-resolution angle-resolved photoemission results are presented which allow us to determine the complete Fermi surfaces for the surface-localized electronic levels on the clean and hydrogencovered Mo(011) surfaces. Similar to previously presented data for W(011), we observe a total of three distinct closed hole orbits and one closed electron orbit. The hole orbits are elliptical and are centered on different projections of the same bulk Fermi-surface ellipsoid. They are located at the center and along each … Show more

“…[1][2][3][4][5][6][7][8][9][10][11] In addition to being easy to clean, Mo and W surfaces exhibit surface states, surface reconstructions, as well as interesting electronic and structural changes during chemisorption. They have thus been favorite platforms for studying surface phenomena for many decades.…”

“…While the tungsten surface in various orientations has been investigated extensively by both a variety of theoretical methods and surface techniques, comparatively less detailed information about the molybdenum surfaces is available. [1][2][3][4][5][6][7][8][9][10][11] In many respects, the structural properties of the molybdenum surface are similar to those of tungsten, but there are also subtle differences. For example, the clean ͑100͒ tungsten surface shows a (ͱ2ϫͱ2)R45°reconstruction, while more complex reconstructions of the clean Mo͑100͒ surface have been observed.…”

“…For the clean (110) surfaces of W and Mo no indication of an anomaly is found, but this only appears when the surfaces are covered with a full layer of hydrogen. Nevertheless, a close link between the surface phonon anomalies and H vibrations seems to be ruled out, since the HAS spectra remain practically unchanged when deuterium is adsorbed instead of hydrogen [2,3].Angular resolved photoemission (ARP) studies have been performed by Kevan and coworkers [12][13][14] for clean and hydrogen covered W (110) and Mo (110). These studies give no evidence of the existence of parallel segments of the Fermi-surface contours separated by wave vectors comparable with the HAS determined critical wave vectors and thus there appeared to be compelling reason for abandoning the nesting mechanism as a possible origin of the anomalies seen in HAS.…”
