Optically Induced Thermal Runaway in Phase-Change VO2 Nanostructures
Jiří Kabát, Peter Kepič, Andrea Konečná +1
While thermal runaway occurs across diverse physical disciplines, its presence in subwavelength phase-change photonics remains unexplored because existing thermo-optical models bre…
Optimal conditions for detecting optical dichroism at the nanoscale by electron energy-loss spectroscopy
Marek Zálešák, Martin Ošmera, Martin Hrtoň +1
The emergence of optical circular dichroism in chiral nanoscale and molecular systems provides not only a way for analyzing the sample chirality itself but also additional degrees…
Tuning of Localized Surface Plasmons in Vanadium Dioxide Nanoparticles via Size and Insulator-Metal Transition
Jiří Kabát, Rostislav Řepa, Jordan A. Hachtel +5
Vanadium dioxide has been identified as a promising phase-changing material for use in tunable plasmonic devices. In this study, we present a comprehensive modal analysis of single…
Coexisting phases of individual VO nanoparticles for multilevel nanoscale memory
Peter Kepič, Michal Horák, Jiří Kabát +4
Vanadium dioxide (VO) has received significant interest in the context of nanophotonic metamaterials and memories owing to its reversible insulator-metal transition associated…
