Publikováno v: Lizzit, S, Baraldi, A, Grütter, C, Bilgram, J H & Hofmann, P 2009, ' The surface phase transition and low-temperature phase of a-Ga(010) studiedby SPA-LEED ', Surface Science, vol. 603, pp. 3222-3226 . https://doi.org/10.1016/j.susc.2009.09.006

The order–disorder phase transition on the α-Ga(0 1 0) ( 2 2 × 2 ) R 45 ° structure was studied by spot-profile analysis low energy electron diffraction (SPA-LEED). A low temperature diffraction pattern reveals a small splitting of the overlayer

Electron-Lattice Interaction onα−Ga(010)

Autor: Ch. Grütter, Philip Hofmann, Yong Q. Cai, J. H. Bilgram

Publikováno v: Physical Review Letters

We have investigated the (010) surface of $\ensuremath{\alpha}\ensuremath{-}\mathrm{Ga}$ by angle-resolved photoemission and low energy electron diffraction. We find a surface state around the $\overline{C}$ point of the surface Brillouin zone. The e

Surface Structure ofα-Ga(010)

Autor: J. H. Bilgram, D. A. Walko, Ch. Grütter, I. K. Robinson

Publikováno v: Physical Review Letters. 81:626-629

We have determined the surface structure of {alpha}-Ga(010) near its melting point using x-ray diffraction. Of the two possible ideal ways to form the (010) surface, we find that the true surface is formed by cutting through dimer bonds (i.e., betwee

Surface melting of gallium single crystals

Autor: J. H. Bilgram, Ch. Grütter, R. Trittibach

Publikováno v: Physical Review B. 50:2529-2536

Optical properties of the Ga(010), Ga(111), and Ga(112) surfaces have been studied. Single crystals have been grown at UHV conditions and in situ ellipsometric techniques have been applied. On the Ga(112) surface the formation of a quasiliquid layer

Bulk and surface premelting phenomena inα-gallium

Autor: Wolfgang Donner, Ch. Grütter, Helmut Dosch, J. H. Bilgram, Harald Reichert, A. Rühm

Publikováno v: Physical Review B. 68

We present a detailed x-ray study of premelting phenomena in the bulk and at the (100) surface of $\ensuremath{\alpha}$-gallium single crystals using conventional and grazing angle diffraction. In the bulk we find anisotropic anomalies of the lattice

α-Ga(010) surface reconstruction: A LEED structural analysis of the(1×1)room temperature and(22×2)R45°low-temperature structures

Autor: S. Moré, E. A. Soares, M. A. Van Hove, S. Lizzit, A. Baraldi, Ch. Grütter, J. H. Bilgram, Ph. Hofmann

Publikováno v: Physical Review B. 68

The geometric structure of the alpha-Ga(010)-(1x1) room temperature structure and its (2rt2xrt2) R45 degrees reconstruction below 232 K have been determined using Low Energy Electron Diffraction (LEED) structure analysis. The room temperature structu

Publikováno v: Physical Review B. 67

We have determined the electronic structure of $\ensuremath{\alpha}$-Ga using angle-resolved photoemission from the $\ensuremath{\alpha}$-Ga(010) surface. Data were collected both at 78 K and at 273 K, i.e., below and above the temperature of the sur

Publikováno v: Physical Review B. 67

The interplay between the surface phase transition on \ensuremath{\alpha}-Ga(010) and the electronic structure was studied by temperature-dependent high-resolution angle-resolved photoemission using synchrotron radiation. The transition causes severa
