Morphology of Sn Films Grown on the Fivefold Surface of Icosahedral Al63Cu24Fe13 Investigated by Scanning Tunneling Microscopy
نویسندگان
چکیده
Sn film growth on the fivefold surface of icosahedral Al63Cu24Fe13 has been investigated by employing scanning tunneling microscopy. For about monolayer coverage, the deposited Sn forms a layer of monoatomic height. A Fourier transform of the layer’s structure reveals quasicrystalline long range order. At higher coverage, flat-topped clusters of uniform heights are formed. The clusters preferentially grow at the step edges.

Quantum size effects in metal thin films grown on quasicrystalline substrates.
We have investigated by scanning tunneling microscopy the growth of Bi and Ag thin films on the fivefold surface of Al63Cu24Fe13 and Al72Pd19.5Mn8.5 quasicrystal, respectively. For both systems, we observe the formation of islands with magic height, corresponding to the stacking of a specific number of atomic layers. We interpret this unusual growth morphology in terms of quantum size effects, ...
متن کاملReal-space observation of quasicrystalline Sn monolayer formed on the fivefold surface of icosahedral AlîŠ ̧CuîŠ ̧Fe quasicrystal
We investigate a thin Sn film grown at elevated temperatures on the fivefold surface of an icosahedral AlCuFe quasicrystal by scanning tunneling microscopy (STM). At about one monolayer coverage, the deposited Sn is found to form a smooth film of height consistent with one-half of the lattice constant of the bulk Sn. Analysis based on the Fourier transform and autocorrelation function derived...
متن کاملScanning tunneling microscopy characterization of the surface morphology of copper films grown on mica and quartz
The morphology of copper films grown on quartz, mica, and Ti/quartz has been investigated by means of scanning tunneling microscopy (STM). Films grown on quartz, both bare and pre-plated with titanium, are characterized by self-affine fractal scaling behavior over the length scale of 10 ̈500 nm, while films grown on mica are not. Annealing of the films to 340 -C reduces the root-mean-square (RMS...
متن کاملScanning Tunneling Microscopy and Tunneling Luminescence of the Surface of GaN Films Grown by Vapor Phase Epitaxy
We report scanning tunneling microscopy (STM) images of surfaces of GaN films and the observation of luminescence from those films induced by highly spatially localized injection of electrons or holes using STM. This combination of scanning tunneling luminescence (STL) with STM for GaN surfaces and the ability to observe both morphology and luminescence in GaN is the first step to investigate p...
متن کاملNano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy
ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...
