Bulk electronic structure of quasicrystals.
We use hard x-ray photoemission to resolve a controversial issue regarding the mechanism for the formation of quasicrystalline solids, i.e., the existence of a pseudogap at the Fermi level. Our data from icosahedral fivefold Al-Pd-Mn and Al-Cu-Fe quasicrystals demonstrate the presence of a pseudogap, which is not observed in surface sensitive low energy photoemission because the spectrum is aff...
متن کاملBulk electronic structure of metals resolved with scanning tunneling microscopy.
We demonstrate that bulk band structure can have a strong influence in scanning tunneling microscopy measurements by resolving electronic interference patterns associated with scattering phenomena of bulk states at a metal surface and reconstructing the bulk band topology. Our data reveal that bulk information can be detected because states at the edge of the surface-projected bulk band have a ...
متن کاملElectronic structure and bulk spin-valve behavior in Ca3Ru2O7.
Density functional calculations of the fermiology and magnetic properties of Ca3Ru2O7 reveal an unusual state: a bulk spin valve. The ground state consists of nearly half-metallic bilayers stacked antiferromagnetically with a weak coupling. Out of plane transport is very strongly suppressed by the antiferromagnetic alignment, which can be destroyed in favor of ferromagnetism at low energy cost....
متن کاملElectronic Band Structure of Bulk and Monolayer V2O5
Vanadium oxide (V2O5) is a material that can be fabricated as a thin film of only a few atomic layers thick during mechanical exfoliation due to the weak interlayer interactions, much like how graphene is created. During this project we looked at the band structure of both the bulk and mono-layered V2O5. We used computer software called ABINIT, which is installed on the high performance compute...
متن کاملElectronic structure of quasicrystalline surfaces: Effects of surface preparation and bulk structure
We elucidate the nature of the surface electronic properties of quasicrystalline Al-Pd-Mn. We do this by using photoelectron and Auger electron spectroscopies, and by making a variety of comparisons—across types of bulk samples, and across methods of surface preparation. The main conclusions are these: (i) The narrow Mn 2p3/2core-level line observed in the icosahedral phase is a fingerprint of ...
