Photoresponsivity enhancement in monolayer MoS by rapid O:Ar plasma treatment
Jakub Jadwiszczak, Gen Li, Conor P. Cullen +5
We report up to ten-fold enhancement of the photoresponsivity of monolayer MoS by treatment with O:Ar (1:3) plasma. We characterize the surface of plasma-exposed MoS by…
Machine learning density functional theory for the Hubbard model
James Nelson, Rajarshi Tiwari, Stefano Sanvito
The solution of complex many-body lattice models can often be found by defining an energy functional of the relevant density of the problem. For instance, in the case of the Hubbar…
Quantifying the factors limiting rate-performance in battery electrodes
Ruiyuan Tian, Sang-Hoon Park, Paul J. King +4
A significant problem associated with batteries is the rapid reduction of charge-storage capacity with increasing charge/discharge rate. For example, improving this rate-performanc…
Antiresonance-Like Behavior in Carrier-Envelope-Phase-Sensitive Optical-Field Photoemission from Plasmonic Nanoantennas
P. D. Keathley, W. P. Putnam, P. Vasireddy +4
Given the quasi-static nature of optical-field emission and the nontrivial dependence of the emission rate on the instantaneous electric field strength, the CEP-sensitive component…
Magnetocrystalline anisotropy and exchange probed by high-field anomalous Hall effect in fully-compensated half-metallic Mn2RuxGa thin films
Ciarán Fowley, Karsten Rode, Yong-Chang Lau +12
Magnetotransport is investigated in thin films of the half-metallic ferrimagnet MnRuGa in pulsed magnetic fields of up to 58 T. A non-vanishing Hall signal is observed over…
Environmental effects on the electrical characteristics of back-gated WSe2 field effect transistors
Francesca Urban, Lisanne Peters, Nadia Martucciello +2
We study the effect of polymer coating, pressure and temperature on the electrical characteristics of monolayer WSe2 back-gated transistors with quasi-ohmic Ni/Au contacts. We find…
A WSe2 vertical field emission transistor
Antonio Di Bartolomeo, Francesca Urban, Maurizio Passacantando +6
We report the first observation of gate-controlled field emission current from a tungsten diselenide (WSe2) monolayer, synthesized by chemical-vapour deposition on SiO2/Si substrat…
Antiferromagnetic Single-layer Spin-Orbit Torque Oscillators
Roberto E. Troncoso, Karsten Rode, Plamen Stamenov +2
We show how a charge current through a single antiferromagnetic layer can excite and control self-oscillations. Sustained oscillations with tunable amplitudes and frequencies are p…
AFLOW-CHULL: Cloud-oriented platform for autonomous phase stability analysis
Corey Oses, Eric Gossett, David Hicks +10
prediction of phase stability of materials is a challenging practice, requiring knowledge of all energetically-competing structures at formation conditions. Lar…
Optimized single-layer MoS2 field-effect transistors by non-covalent functionalisation
HyunJeong Kim WungYeon Kim, Maria O'Brien, Niall McEvoy +6
Field-effect transistors (FETs) with non-covalently functionalised molybdenum disulfide (MoS2) channels grown by chemical vapour deposition (CVD) on SiO2 are reported. The dangling…
Electron trapping by neutral pristine ferroelectric domain walls in BiFeO
Sabine Körbel, Jirka Hlinka, Stefano Sanvito
First-principles calculations for pristine neutral ferroelectric domain walls in BiFeO reveal that excess electrons are selectively trapped by the domain walls, while holes are…
Emergence of Winner-takes-all Connectivity Paths in Random Nanowire Networks
Hugh G. Manning, Fabio Niosi, Claudia Gomes da Rocha +8
Nanowire networks are promising memristive architectures for neuromorphic applications due to their connectivity and neurosynaptic-like behaviours. Here, we demonstrate a self-simi…
Spin-Polarized Tunneling through Chemical Vapor Deposited Multilayer Molybdenum Disulfide
André Dankert, Parham Pashaei, M. Venkata Kamalakar +10
The two-dimensional (2D) semiconductor molybdenum disulfide (MoS2) has attracted widespread attention for its extraordinary electrical, optical, spin and valley related properties.…
Highly sensitive electromechanical piezoresistive pressure sensors based on large-area layered PtSe films
Stefan Wagner, Chanyoung Yim, Niall McEvoy +8
Two-dimensional (2D) layered materials are ideal for micro- and nanoelectromechanical systems (MEMS/NEMS) due to their ultimate thinness. Platinum diselenide (PtSe), an excit…
Spectroscopic size and thickness metrics for liquid-exfoliated h-BN
Aideen Griffin, Andrew Harvey, Brian Cunningham +8
For many 2D materials, optical and Raman spectra are richly structured, and convey information on a range of parameters including nanosheet size and defect content. By contrast, th…
XDFT: an efficient first-principles method for neutral excitations in molecules
Subhayan Roychoudhury, Stefano Sanvito, David D. O'Regan
State-of-the-art methods for calculating neutral excitation energies are typically demanding and limited to single electron-hole pairs and their composite plasmons. Here we introdu…
A simple descriptor for energetics at fcc-bcc metal interfaces
Linda A. Zotti, Stefano Sanvito, David D. O'Regan
We have developed a new and user-friendly interface energy calculation method that avoids problems deriving from numerical differences between bulk and slab calculations, such as t…
The role of spin in the calculation of Hubbard and Hund's parameters from first principles
Edward B. Linscott, Daniel J. Cole, Michael C. Payne +1
The density functional theory (DFT)+ method is a pragmatic and effective approach for calculating the ground-state properties of strongly-correlated systems, and linear response…
Wannier-function-based constrained DFT with nonorthogonality-correcting Pulay forces in application to the reorganization effects in graphene-adsorbed pentacene
Subhayan Roychoudhury, David D. O'Regan, Stefano Sanvito
Pulay terms arise in the Hellman-Feynman forces in electronic structure calculations when one employs a basis set made of localized orbitals that move with their host atoms. If the…
