Inverse determination of light-matter coupling in disordered systems from transmittance spectra
Thales F. Macedo, Julián Faúndez, Antônio S. Coelho +4
We investigate quantum inverse problems in one-dimensional (1D) electronic disordered systems strongly coupled to optical cavities. More specifically, we consider the Anderson and…
Monolayer Capping Provides Close to Optimal Resistance to Laser Dewetting of Au Films
Christopher P. Murray, Daniyar Mamyraimov, Mugahid Ali +5
Next-generation heat-assisted magnetic recording (HAMR) relies on fast, localized heating of the magnetic medium during the write process. Au plasmonic near-field transducers are a…
Deterministic multi-level spin orbit torque switching using He+ microscopy patterning
Jinu Kurian, Aleena Joseph, Salia Cherifi-Hertel +7
He ion irradiation is used to pattern multiple areas of Pt/Co/W films with different irradiation doses in Hall bars. The resulting perpendicular magnetic anisotropy landscape e…
Towards Chirality Control of Graphene Nanoribbons Embedded in Hexagonal Boron Nitride
Hui Shan Wang, Lingxiu Chen, Kenan Elibol +16
The integrated inplane growth of two dimensional materials with similar lattices, but distinct electrical properties, could provide a promising route to achieve integrated circuitr…
Helium Ion Microscopy for Reduced Spin Orbit Torque Switching Currents
Peter Dunne, Ciaran Fowley, Gregor Hlawacek +11
Spin orbit torque driven switching is a favourable way to manipulate nanoscale magnetic objects for both memory and wireless communication devices. The critical current required to…
Time-resolved impurity-invisibility in graphene nanoribbons
Riku Tuovinen, Michael A. Sentef, Claudia Gomes da Rocha +1
We investigate time-resolved charge transport through graphene nanoribbons supplemented with adsorbed impurity atoms. Depending on the location of the impurities with respect to th…
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…
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…
Multi-scale modelling of current-induced switching in magnetic tunnel junctions using ab initio spin transfer torques
Matthew O. A. Ellis, Maria Stamenova, Stefano Sanvito
There exists a significant challenge in developing efficient magnetic tunnel junctions with low write currents for non-volatile memory devices. With the aim of analysing potential…
Theoretical evaluation of [V(α-CS)] as nuclear-spin sensitive single-molecule spin transistor
Salvador Cardona-Serra, Alejandro Gaita-Ariño, Maria Stamenova +1
In a straightforward application of molecular nanospintronics to quantum computing, single-molecule spin transistors can be used to measure and control nuclear spin qubits. A jump…
Programmable graphene doping via electron beam irradiation
Yangbo Zhou, Jakub Jadwiszczak, Darragh Keane +3
Graphene is a promising candidate to succeed silicon based devices and doping holds the key to graphene electronics. Conventional doping methods through surface functionalization o…

The ultra-fast demagnetization of small iron clusters initiated by an intense optical excitation is studied with time-dependent spin density functional theory (TDSDFT). In particul…
Charge transfer energies of benzene physisorbed on a graphene sheet from constrained density functional theory
Subhayan Roychoudhury, Carlo Motta, Stefano Sanvito
Constrained density functional theory (CDFT) is used to evaluate the energy level alignment of a benzene molecule as it approaches a graphene sheet. Within CDFT the problem is conv…
