Platinum is a Photocatalyst: Large Visible-Light Quantum Efficiency Revealed
Olivier Henrotte, Yin Chak Wong, Jordan Edwards +5
Metal-semiconductor junctions in optoelectronic devices are commonly engineered to promote charge separation. In Pt/TiO2 Schottky junctions, Pt is typically regarded as a catalytic…
Atomistic Theory of Plasmon-Induced Hot-carriers in Al Nanoparticles
Gengyue Dong, Simão João, Hanwen Jin +1
Hot electrons and holes generated from the decay of localized surface plasmons (LSPs) in aluminum nanostructures have significant potential for applications in photocatalysis, phot…
Reconciling Kubo and Keldysh Approaches to Fermi-Sea-Dependent Nonequilibrium Observables: Application to Spin Hall Current and Spin-Orbit Torque in Spintronics
Simao M. Joao, Marko D. Petrovic, J. M. Viana Parente Lopes +2
Quantum transport studies of spin-dependent phenomena in solids commonly employ the Kubo or Keldysh formulas for the nonequilibrium density operator in the steady-state linear-resp…
Hot Carriers from Intra- and Interband Transitions in Gold-Silver Alloy Nanoparticles
Shreyas Ramachandran, Simao Joao, Hanwen Jin +1
Hot electrons and holes generated from the decay of localized surface plasmons in metallic nanoparticles can be harnessed for applications in solar energy conversion and sensing. I…
Magnetotransport properties of a twisted bilayer graphene in the presence of external electric and magnetic field
Priyanka Sinha, Ayan Mondal, Simão Meneses João +1
We extensively investigate the electronic and transport properties of a twisted bilayer graphene when subjected to both an external perpendicular electric field and a magnetic fiel…
Twist- and gate-tunable proximity spin-orbit coupling, spin relaxation anisotropy, and charge-to-spin conversion in heterostructures of graphene and transition-metal dichalcogenides
Klaus Zollner, Simão M. João, Branislav K. Nikolić +1
We present a DFT-based investigation of the twist-angle dependent proximity spin-orbit coupling (SOC) in graphene/TMDC structures. We find that for Mo-based TMDCs the proximity val…
Crystal Facet Effect in Plasmonic Catalysis
Yicui Kang, Simão M. João, Rui Lin +10
In the realm of plasmonic catalytic systems, much attention has been devoted to the plasmon-derived mechanisms, yet the influence of nanoparticles' crystal facets in this type of p…
Atomistic theory of hot carrier relaxation in large plasmonic nanoparticles
S. M. João, Hanwen Jin, Johannes Lischner
Recently, there has been significant interest in harnessing hot carriers generated from the decay of localized surface plasmons in metallic nanoparticles for applications in photoc…
Anomalous Transport Signatures in Weyl Semimetals with Point Defects
J. P. Santos Pires, Simão M. João, Aires Ferreira +2
We present the first theoretical study of transport properties of Weyl semimetals with point defects. Focusing on a class of time-reversal symmetric Weyl lattice models, we show th…
High-resolution real-space evaluation of the self-energy operator of disordered lattices: Gade singularity, spin-orbit effects and p-wave superconductivity
Simão M. João, J. M. Viana Parente Lopes, Aires Ferreira
Disorder is a key factor influencing the behavior of condensed states of matter, however the true extent of its impact is generally difficult to determine due to the prominent role…
