Fermi states and anisotropy of Brillouin zone scattering in the decagonal Al-Ni-Co quasicrystal

Quasicrystals (QCs) are intermetallic alloys that have excellent long-range order but lack translational symmetry in at least one dimension. The valence band electronic structure near the Fermi energy E-F in such materials is of special interest since it h ...

Investigation of interactions in two-dimensional electron gases with angular resolved photoemission spectroscopy

Carola Strasser

In this thesis, angular resolved photoemission spectroscopy (ARPES) is used to study the electronic structure of different two-dimensional electron systems (2DES). This technique is very surface sensitive and the most direct method to probe the surface ban ...

Ultrafast Optical Control of the Electronic Properties of ZrTe5

Marco Grioni, Arnaud Magrez, Helmuth Berger, Philippe Bugnon, Alberto Crepaldi

We report on the temperature dependence of the ZrTe5 electronic properties, studied at equilibrium and out of equilibrium, by means of time and angle resolved photoelectron spectroscopy. Our results unveil the dependence of the electronic band structure ac ...

Energetics of native point defects in GaN: A density-functional study

Alfredo Pasquarello, Giacomo Francesco Leonardo Miceli

We study the formation energies of native point defects in GaN through density-functional theory. In our first-principles scheme, the band edges are positioned in accord with hybrid density functional calculations, thus yielding a band-gap in agreement wit ...

Probing two- and three-dimensional electrons in MgB2 with soft x-ray angle-resolved photoemission

Thorsten Schmitt, Martin Mansson

electronic band structure of MgB2 involves a unique combination of two-and three-dimensional (3D) electrons derived from the boron sigma and pi states, respectively. We have mapped out the sigma and pi bands over the complete Brillouin zone, including the ...

Atomic Scale Microstructure and Properties of Se-Deficient Two-Dimensional MoSe2

Andras Kis, Oleg Yazyev, Hannu-Pekka Komsa, Ming-Wei Chen, Artem Pulkin

We study the atomic scale microstructure of non-stoichiometric two-dimensional(2D) transition metal dichalcogenide MoSe2-x, by employing aberration-corrected high-resolution transmission electron microscopy. We show that a Se-deficit in single layers of Mo ...

Bi2Te3-xSex series studied by resistivity and thermopower

László Forró, Ana Akrap

We study the detailed temperature and composition dependence of the resistivity, rho(T), and thermopower, S(T), for a series of layered bismuth chalcogenides Bi2Te3-xSex, and report the stoichiometry dependence of the optical band gap. In the resistivity o ...

Pressure tuning the Fermi level through the Dirac point of giant Rashba semiconductor BiTeI

Helmuth Berger

We report measurements of Shubnikov-de Haas oscillations in the giant Rashba semiconductor BiTeI under applied pressures up to similar to 2GPa. We observe one high frequency oscillation at all pressures and one low frequency oscillation that emerges betwee ...

Temperature-dependent electron-phonon coupling in La_{2−x}Sr_{x}CuO_{4} probed by femtosecond x-ray diffraction

Majed Chergui, Henrik Moodysson Rønnow, Fabrizio Carbone, Paul Beaud, Krunoslav Prsa, Giulia Fulvia Mancini, Mathieu Julien Gino Cottet, Kazimierz Conder

The strength of the electron-phonon coupling parameter and its evolution throughout a solid's phase diagram often determines phenomena such as superconductivity, charge- and spin-density waves. Its experimental determination relies on the ability to distin ...

Elemental Topological Insulator with Tunable Fermi Level: Strained alpha-Sn on InSb(001)

Jan Hugo Dil

We report on the epitaxial fabrication and electronic properties of a topological phase in strained alpha-Sn on InSb. The topological surface state forms in the presence of an unusual band order not based on direct spin-orbit coupling, as shown in density ...
