Spin-resolved band structure of a densely packed Pb monolayer on Si(111)

Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli

Monolayer structures of Pb on Si(111) attracted recently considerable interest as superconductivity was found in these truly two-dimensional (2D) structures. In this study, we analyzed the electronic surface band structure of the so-called striped incommen ...

Fermi-level pinning and intrinsic surface states of Al1-xInxNd(10(1)over-bar0) surfaces

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté

The electronic structure of Al1-xInxNd(10 (1) over bar0) surfaces is investigated by cross-sectional scanning tunneling spectroscopy and density functional theory calculations. The surface exhibits empty Al and/or In-derived dangling bond states, which are ...

Recent advances in large-scale synthesis of graphene and other 2D materials have underscored the importance of local defects such as dislocations and grain boundaries (GBs), and especially their tendency to alter the electronic properties of the material. ...

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 ...

1T-TiSe2 is a quasi-two-dimensional transition metal dichalcogenide, which exhibits a charge density wave transition at a critical temperature of similar to 200 K as well as low-temperature superconductivity induced by pressure or intercalation. The electr ...

Angle-resolved synchrotron photoemission and density functional theory on the iridium modified Si(111) surface

Jan Hugo Dil

The physical and electronic properties of the Ir modified Si(1 1 1) surface have been investigated with the help of angle resolved photoemission spectroscopy and density functional theory. The surface consists of Ir-ring clusters that form a root 7 x root ...

Bridging density-functional and many-body perturbation theory: Orbital-density dependence in electronic-structure functionals

Nicola Marzari, Matteo Cococcioni, Andrea Ferretti

Energy functionals which depend explicitly on orbital densities, rather than on the total charge density, appear when applying self-interaction corrections to density-functional theory; this is, e.g., the case for Perdew-Zunger and Koopmans-compliant funct ...

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 ...

Recent theoretical calculations and experimental results suggest that the strongly correlated material SmB6 may be a realization of a topological Kondo insulator. We have performed an angle-resolved photoemission spectroscopy study on SmB6 in order to eluc ...

Disentanglement of Surface and Bulk Rashba Spin Splittings in Noncentrosymmetric BiTeI

Jan Hugo Dil, Thorsten Schmitt, Vladimir N. Strocov, Stefan Peter Muff

BiTeI has a layered and noncentrosymmetric structure where strong spin-orbit interaction leads to a giant Rashba spin splitting in the bulk bands. We present direct measurements of the bulk band structure obtained with soft x-ray angle-resolved photoemissi ...
