Modeling Ferro- and Antiferromagnetic Interactions in Metal-Organic Coordination Networks

Klaus Kern, Sebastian Stepanow, Tzu-Chun Tseng, Violetta Sessi, Alexander Langner, Nasiba Abdurakhmanova, Christopher Seiji Kley

Magnetization curves of two rectangular metalorganic coordination networks formed by the organic ligand TCNQ (7,7,8,8-tetracyanoquinodimethane) and two different (Mn and Ni) 3d transition metal atoms [M(3d)] show marked differences that are explained using ...

Tuning electronic correlations in transition metal pnictides: Chemistry beyond the valence count

Thorsten Schmitt, Joël Mesot, Elia Razzoli, Philipp Aebi

The effects of electron-electron correlations on the low-energy electronic structure and their relationship with unconventional superconductivity are central aspects in the research on iron-based pnictide superconductors. Here we use soft x-ray angle-resol ...

Camelback-shaped band reconciles heavy-electron behavior with weak electronic Coulomb correlations in superconducting TlNi2Se2

Joël Mesot

Combining photoemission spectroscopy, Raman spectroscopy, and first-principles calculations, we characterize superconducting TlNi2Se2 as a material with weak electronic Coulomb correlations leading to a bandwidth renormalization of 1.4. We identify a camel ...

Electron mobility extraction in triangular gate-all-around Si nanowire junctionless nMOSFETs with cross-section down to 5 nm

Mihai Adrian Ionescu, Jean-Michel Sallese, Wladyslaw Grabinski, Mohammad Najmzadeh, Matthieu Berthomé

In this paper, we report the first systematic study on electron mobility extraction in equilateral triangular gate-all-around Si nanowire junctionless nMOSFETs with cross-section down to 5 nm. 1 x 10(19) cm(-3) n-type channel doping, 5-20 nm Si nanowire wi ...

Spin lifetime of itinerant electrons in chemically synthesized graphene multi-layers

László Forró, Bálint Náfrádi

A chemically synthesized graphitic material where the structural coherence between the layers is missing approximates very well the assembly of graphene sheets. Our multi-frequency (9.4-420 GHz) electron spin resonance (ESR) study clearly identifies itiner ...

Two-dimensional short-range interacting attractive and repulsive Fermi gases at zero temperature

Gianluca Bertaina

We study a two-dimensional two-component Fermi gas with attractive or repulsive short-range interactions at zero temperature. We use Diffusion Monte Carlo with Fixed Node approximation in order to calculate the energy per particle and the opposite spin pai ...

Free-electron gas at charged domain walls in insulating BaTiO3

Nava Setter, Alexander Tagantsev, Tomas Sluka, Petr Bednyakov

Hetero interfaces between metal-oxides display pronounced phenomena such as semiconductor-metal transitions, magnetoresistance, the quantum hall effect and superconductivity. Similar effects at compositionally homogeneous interfaces including ferroic domai ...

Dynamic structure factors of Cu, Ag, and Au: Comparative study from first principles

Cécile Hébert, Audrius Alkauskas, Simon Schneider

We present a comparative theoretical and experimental study of dynamic structure factors (momentum-dependent loss functions) of the noble metals Cu, Ag, and Au in the energy range of 0-60 eV. The emphasis is on theoretical results that are compared with ne ...

Mobility Extraction Assessment in GAA Si NW JL FETs with Cross-Section Down to 5 nm

Mihai Adrian Ionescu, Jean-Michel Sallese, Wladyslaw Grabinski, Mohammad Najmzadeh, Matthieu Berthomé

In this paper, we report for the first time, assessment on mobility extraction in equilateral triangular gate-all-around Si nanowire junctionless (JL) nMOSFETs with cross-section down to 5 nm. This analysis was performed in accumulation regime, as a first ...

Inelastic x-ray study of phonon broadening and charge-density wave formation in ortho-II-ordered YBa_{2}Cu_{3}O_{6.54}

Johan Juul Chang

Inelastic x-ray scattering is used to investigate charge-density wave (CDW) formation and the low-energy lattice dynamics of the underdoped high-temperature superconductor ortho-II YBa2Cu3O6.54. We find that, for a temperature similar to 1/3 of the CDW ons ...
