Journal ArticleDOI
"Hot" electrons in metallic nanostructures-non-thermal carriers or heating?
Yonatan Dubi,Yonatan Sivan +1 more
TL;DR: In this article, a coupled Boltzmann-heat model is proposed to study the interplay between illumination and electron distribution in metallic nanostructures. But the model requires only energy conservation and basic thermodynamics, where the electron distribution, and the electron and phonon (lattice) temperatures are determined uniquely.
Journal ArticleDOI
Comment on "Quantifying hot carrier and thermal contributions in plasmonic photocatalysis".
TL;DR: This work identifies experimental flaws that caused overestimation of the hot carrier contribution and fully reproduces their data using a purely thermal Arrhenius law with a fixed activation energy and intensity-dependent heating.
Journal ArticleDOI
Thermal effects – an alternative mechanism for plasmon-assisted photocatalysis
TL;DR: In this article, the authors argue that what appears to be photocatalysis is much more likely thermo-catalysis, driven by the well-known plasmonenhanced ability of illuminated metallic nanoparticles to serve as heat sources.
Journal ArticleDOI
Bound states of nonlinear Schrödinger equations with a periodic nonlinear microstructure
TL;DR: In this paper, the authors consider nonlinear bound states of the nonlinear Schrodinger equation in the presence of a nonlinear periodic microstructure m (N x ).
Journal ArticleDOI
Instability of bound states of a nonlinear Schrödinger equation with a Dirac potential
TL;DR: In this article, the stability of the standing wave solution for a nonlinear Schrodinger equation with a point defect and a power type nonlinearity was studied, and it was shown that the standing-wave solution is stable in H rad 1 (R ) and unstable in H 1 ( R ) under subcritical nonlinearities.
