Dirac fermions at high-index surfaces of bismuth chalcogenide topological insulator nanostructures

Binary bismuth chalcogenides Bi2Se3, Bi2Te3, and related materials are currently being extensively investigated as the reference topological insulators (TIs) due to their simple surface-state band dispersion (single Dirac cone) and relatively large bulk ba ...

Hydrogen on silicene: like or unlike graphene?

Michele Pizzochero

Hydrogenation of free-standing silicene, the two-dimensional allotrope of silicon, is investigated in detail using first-principles methods and compared with the adsorption of H atoms on graphene. Similarly to graphene, chemisorption of a single H atom on ...

Contact potentials, Fermi level equilibration and surface charging

Hubert Girault, Pekka Eero Peljo

This paper focuses on contact electrification from thermodynamic equilibration of the electron electrochemical potentials of two conductors upon contact. The contact potential difference generated in bimetallic macro- and nanosystems, the Fermi level after ...

Impact of Monovalent Cation Halide Additives on the Structural and Optoelectronic Properties of CH3NH3PbI3 Perovskite

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Mohammad Ibrahim Dar, Neha Arora, Marius Franckevicius, Mojtaba Abdi Jalebi, Yuanyuan Hu

The influence of monovalent cation halide additives on the optical, excitonic, and electrical properties of CH3NH3PbI3 perovskite is reported. Monovalent cation halide with similar ionic radii to Pb2+, including Cu+, Na+, and Ag+, have been added to explor ...

Nonstoichiometric Low-Temperature Grown GaAs Nanowires

Anna Fontcuberta i Morral, Federico Matteini, Heidi Andrea Potts, Tao Xu

The structural and electronic properties of nonstoichiometric low-temperature grown GaAs nanowire shells have been investigated with scanning tunneling microscopy and spectroscopy, pump probe reflectivity, and cathodoluminescence measurements. The growth o ...

Tuning the metal-insulator transition in NdNiO3 heterostructures via Fermi surface instability and spin fluctuations

Joël Mesot, Elia Razzoli, Zoran Ristic

We employed in situ pulsed laser deposition (PLD) and angle-resolved photoemission spectroscopy (ARPES) to investigate the mechanism of the metal-insulator transition (MIT) in NdNiO3 (NNO) thin films, grown on NdGaO3(110) and LaAlO3(100) substrates. In the ...

Bulk and surface band structure of the new family of semiconductors BiTeX (X=I, Br, Cl)

Marco Grioni, Arnaud Magrez, Oleg Yazyev, Helmuth Berger, Philippe Bugnon, Alberto Crepaldi, Gabriel Albert Autes, Luca Moreschini, Simon Karl Moser, Jens Christian Johannsen

We present an overview of the new family of semiconductors BiTeX (X = I, Br, Cl) from the perspective of angle resolved photoemission spectroscopy. The strong band bending occurring at the surface potentially endows them with a large flexibility, as they a ...

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 ...

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

Jan Hugo Dil, Thorsten Schmitt

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 ...
