Terrace selection during equilibration at an icosahedral quasicrystal surface
We investigate the equilibration of a fivefold surface of the icosahedral Al‐Pd‐Mn quasicrystal at 900–915 and 925–950 K, using scanning tunneling microscopy. After annealing at the lower temperatures, there is a high density of shallow voids on some terraces but not on others; at 925–950 K, the void-rich terraces are much rarer. The terminations that are consumed by voids exhibit a distinctive...
متن کاملTemperature-induced phase transition observed at a fivefold icosahedral quasicrystalline AlPdMn surface
A switch in symmetry from fivefold to tenfold has been observed at the surface of a monograin icosahedral AlPdMn quasicrystal cut perpendicularly to a fivefold axis as a function of annealing temperature and/or annealing time at a constant temperature. A continuous change in stoichiometry was simultaneously monitored by X-ray photoelectron spectroscopy. The surface structure study was performed...
متن کاملComputational self-assembly of a one-component icosahedral quasicrystal.
Icosahedral quasicrystals (IQCs) are a form of matter that is ordered but not periodic in any direction. All reported IQCs are intermetallic compounds and either of face-centred-icosahedral or primitive-icosahedral type, and the positions of their atoms have been resolved from diffraction data. However, unlike axially symmetric quasicrystals, IQCs have not been observed in non-atomic (that is, ...
متن کاملIdeal AlMnSi quasicrystal : a structural model with icosahedral clusters
A model for Al(Si)Mn quasicrystals is proposed. It is characterized by pure quasiperiodic long range order with icosahedral symmetry. The density and concentrations fit to the experimental values. The interatomic distances are compatible with crystallographic data and compare well to the related 03B1 phase. A large number of icosahedral clusters (Mackay icosahedra) are present in the model. J. ...
متن کاملThe local atomic quasicrystal structure of the icosahedral Mg25Y11Zn64 alloy
A local and medium range atomic structure model for the face centred icosahedral (fci) Mg25Y11Zn64 alloy has been established in a sphere of r = 27 Å. The model was refined by least squares techniques using the atomic pair distribution (PDF) function obtained from synchrotron powder diffraction. Three hierarchies of the atomic arrangement can be found: (i) five types of local coordination polyh...
