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…
Controlled dewetting and phase transition hysteresis of VO2 nanostructures
Peter Kepič, Petra Kalousková, Tomáš Šikola +1
As artificial intelligence continues to grow, so does the need for more efficient ways to process data. Besides moving from electronic to photonic circuits, a promising approach is…
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…
Structural color filters with compensated angle-dependent shifts
Katarína Rovenská, Filip Ligmajer, Beáta Idesová +4
Structural color filters use nano-sized elements to selectively transmit incident light, offering a scalable, economical and environmentally friendly alternative to traditional pig…
Analytical electron microscopy analysis of insulating and metallic phases in nanostructured vanadium dioxide
Jan Krpenský, Michal Horák, Jiří Kabát +4
Vanadium dioxide (VO) is a strongly-correlated material that exhibits insulator-to-metal transition (IMT) near room temperature, which makes it a promising candidate for applic…
Pulsed laser deposition of Sb2S3 films for phase-change tunable nanophotonics
Peter Kepič, Petr Liška, Beáta Idesová +3
Non-volatile phase-change materials with large optical contrast are essential for future tunable nanophotonics. Antimony trisulfide (Sb2S3) has recently gained popularity in this f…
Optically tunable Mie-resonance VO2 nanoantennas for metasurfaces in the visible
Peter Kepič, Filip Ligmajer, Martin Hrtoň +4
Metasurfaces are ultrathin nanostructured surfaces that can allow arbitrary manipulation of light. Implementing dynamic tunability into their design could allow the optical functio…
