Fullerene adsorption on intermetallic compounds of increasing structural complexity

Abstract

Compared to elemental crystals (Al, Cu, Ag, etc.), the local atomic arrangement within Al-based complex intermetallics is usually best described by highly symmetric clusters decorating the unit cell. With the latter containing tens to several thousand atoms (or an infinite number for the case of quasicrystals), this translates to structurally complex surfaces exhibiting unique potential energy landscapes. This review will focus on the different studies reporting the adsorption of C

Influence of differences in orientational planar density on the growth of Pb on the i-Ag–In–Yb quasicrystal

“…Adsorption on quasicrystal surfaces often leads to the observation of interesting phenomena, including pseudomorphic growth of adsorbates or the observation of unique growth modes [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. In particular, the high symmetry surfaces of the icosahedral (i-)Ag-In-Yb quasicrystal have proven a fruitful playground [15][16][17][18][19].…”

“…The i-Ag-In-Yb quasicrystal consists of a quasiperiodic arrangement of 'Tsai'-type clusters, a hierarchical system of atomic shells with icosahedral symmetry which are joined by rhombohedral 'glue' units [20]. In the i-Ag-In-Yb system, the shells are arranged as in figure 1 where an Ag/In rhombic triacontahedron (red) contains an Ag/In icosidodecahedron (blue), 3 Author to whom any correspondence should be addressed.…”

Origin of C60 surface reconstruction resolved by atomic force microscopy

“…The origin of this apparent surface reordering, and the existence, or lack thereof, of a vacancy reconstruction has been intensely debated for decades. Scanning tunnelling microscopy (STM) has provided valuable insight into this highly substrate dependent [7] problem, identifying patterns of bright and dark molecules across many surfaces including Au(111) [1,[8][9][10],…”
