Disentangling bulk and surface Rashba effects in ferroelectric alpha-GeTe

Macroscopic ferroelectric order in alpha-GeTe with its noncentrosymmetric lattice structure leads to a giant Rashba spin splitting in the bulk bands due to strong spin-orbit interaction. Direct measurements of the bulk band structure using soft x-ray angle ...

In situ photoelectron spectroscopic characterization of reactively sputtered, doped vanadium oxide thin films

Andreas Schueler, Anna Krammer, Rosendo Sanjines, Olivia Valérie Charlotte Bouvard

Thin films of pure vanadium oxide (VOx) and Ge doped vanadium oxide (VOx:Ge) have been deposited by reactive magnetron sputtering on Si (100) substrates. These films were characterized by means of in situ X-ray photoelectron spectroscopy and ultraviolet ph ...

Free-standing electronic character of monolayer

Andras Kis, Dumitru Dumcenco, Olivier Renault, Yen-Cheng Kung, Ming-Wei Chen, Hokwon Kim

We have evaluated as-grown MoS2 crystals, epitaxially grown on a monocrystalline sapphire by chemical vapor deposition (CVD), with direct electronic band-structure measurements by energy-filtered k-space photoelectron emission microscopy performed with a c ...

Oxygen defects in amorphous Al2O3: A hybrid functional study

Alfredo Pasquarello, Francesco Ambrosio, Zhendong Guo

The electronic properties of the oxygen vacancy and interstitial in amorphous Al2O3 are studied via ab initio molecular dynamics simulations and hybrid functional calculations. Our results indicate that these defects do not occur in amorphous Al2O3, due to ...

Band Alignment Engineering at Cu2O/ZnO Heterointerfaces

Michael Graetzel, Stanley David Tilley

Energy band alignments at heterointerfaces play a crucial role in defining the functionality of semiconductor devices, yet the search for material combinations with suitable band alignments remains a challenge for numerous applications. In this work, we de ...

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 ...

Surface States Transport in Topological Insulator Bi0.83Sb0.17 Nanowires

Jean-Philippe Ansermet

We investigate the transport properties of topological insulator (TI) nanowires. Single-crystal nanowire samples with diameters ranging from 75 nm to 1.1 m are prepared using high frequency liquid phase casting in a glass capillary; cylindrical single crys ...

A novel quasi-one-dimensional topological insulator in bismuth iodide beta-Bi4I4

László Forró, Marco Grioni, Oleg Yazyev, Gabriel Albert Autes, Luca Moreschini, Andrea Pisoni, Jens Christian Johannsen, Wentao Zhang

Recent progress in the field of topological states of matter(1,2) has largely been initiated by the discovery of bismuth and antimony chalcogenide bulk topological insulators (TIs; refs 3-6), followed by closely related ternary compounds(7-16) and predicti ...

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 ...
