Oxygen-induced surface faceting of the threefold-symmetry surface of icosahedral AlPdMn quasicrystal

Imaging and manipulation of adatoms on an alumina surface by noncontact atomic force microscopy

“…In some cases even the observed structures are close to being identical [51,59]. This is found to be especially pronounced for the films on NiAl (110), Cu-9% Al (111) and FeAl (110) faces, and it appears as if such films also occur on thin NiAl films on Ni (111) [79] and even on Al containing quasicrystals [89,61,60]. This connection is interesting because the peculiar stoichiometry of alumina/NiAl (110) suggested that the structure of the film was a unique product of the properties of both materials, especially regarding the stoichiometry and geometry of the surface cell.…”

“…Besides alumina/NiAl(110) ultrathin epitaxial alumina films have been reported on about 20 other substrates. With no claim to be exhaustive these are alumina films on the (001), ( 110) and ( 111) faces of aluminum [35][36][37], NiAl [38][39][40]17], Ni 3 Al [41][42][43][44][45][46][47][48][49] and FeAl [50,51], on Fe 3 Al(110) [52], CoAl(100) [53,54], γ -TiAl (111) [55][56][57], Cu-9% Al (111) [58,59], decagonal AlCoNi [60] as well as icosahedral AlPdMn and AlCuFe quasicrystals [61][62][63], Ni (111) [64], Mo (100) and (110) [65], Ag (111) [66,67], Ru(0001) [68][69][70], Ta (110) [71], Re(0001) [72,…”
