Quasiperiodic layers of free-electron metals studied using electron diffraction
Using electron diffraction, we show that free-electron metals, such as sodium and potassium, form a highly regular quasiperiodic monolayer on the fivefold surface of icosahedral Al-Pd-Mn and that the quasiperiodicity propagates up to the second layer in sodium. Our photoelectron spectroscopy results show that the quasicrystalline alkali-metal adlayer does not exhibit a pseudogap near the Fermi ...

متن کاملElectron Diffraction Electron Diffraction
This guide sheet outlines a method for the analysis of cubic crystal forms, this being useful to you for interpreting the transmission diffraction pattern produced by scattering electrons off a thin film target of polycrystalline aluminium. The apparatus also contains samples with hexagonal structures. These are pyrolytic graphite targets, and are available both as single crystals and in polycr...
متن کاملElectron Diffraction Using Transmission Electron Microscopy
Electron diffraction via the transmission electron microscope is a powerful method for characterizing the structure of materials, including perfect crystals and defect structures. The advantages of electron diffraction over other methods, e.g., x-ray or neutron, arise from the extremely short wavelength (≈2 pm), the strong atomic scattering, and the ability to examine tiny volumes of matter (≈1...
متن کاملCrystallographic preferred orientations analysis of quartz crystals in Psammite using electron backscatter diffraction,western Ireland
The present study investigates the crystal preferred orientation (CPO) of quartz crystals in psammitic rocks to ascertain the deformationmechanism using electron backscatter diffraction (EBSD) on quartz crystals from north of the Renvyle-Bofin Slide (RBS) nearLetterfrack in western Ireland. Complete crystallographic orientations were determined for several thousand individual quartz crystalsin ...
