Additive and Subtractive Color Filters Based on Birefringent Dielectric Metasurfaces
OndÅej Äervinka, Filip Ligmajer, OndÅej Brunn +3
Dielectric metasurfaces offer a path to high-efficiency optical components at the sub-wavelength scale. In this work, we utilize the wavelength-dependent birefringence of TiO2 nano…
Durable Enhancement of Single-Layer Photoluminescence by Ultraviolet Laser Treatment Under Ambient Conditions
Mahan Bakhshikhah, JiÅà LiÅ¡ka, Rahul Kesarwani +7
Single-layer molybdenum disulfide () possesses significant potential for nanoscale optoelectronics, but achieving high-intensity, long-term-stable photoluminescence (PL) emi…
Work-Function-Resolved Imaging of Relaxation Oscillations and Chemical Spillover in CO Oxidation over Platinum Surfaces
Karel VaÅeka, Michal PotoÄek, Adam OÄkoviÄ +4
Chemical waves of CO oxidation on platinum surfaces exhibit complex spatio-temporal self-oscillations, yet the local electronic mechanisms driving their propagation remain poorly u…
Reconfigurable plasmonic hot spots enabled by composite VO2-gold plasmonic antennas
Rostislav Åepa, JiÅà Kabát, Tomáš Å ikola +1
We theoretically investigate the formation of electric and magnetic hot spots with reconfigurable plasmonic antennas. We consider three material systems offering different levels o…
