Additive and Subtractive Color Filters Based on Birefringent Dielectric Metasurfaces
Ondřej Červinka, Filip Ligmajer, Ondřej 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, Jiří Liška, 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 Vařeka, Michal Potoček, Adam Očkovič +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 Řepa, Jiří Kabát, Tomáš Šikola +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…
Efficient nanoscale imaging of solid-state phase transitions by transmission electron microscopy demonstrated on vanadium dioxide nanoparticles
Michal Horák, Peter Kepič, Jiří Kabát +5
We present annular dark field scanning transmission electron microscopy (ADF-STEM) as an efficient, fast, and non-destructive nanoscale tool for monitoring solid-state phase transi…
Plasmonic lightning-rod effect
Vlastimil Křápek, Rostislav Řepa, Michael Foltýn +2
The plasmonic lightning-rod effect refers to the formation of a strong electric near field of localized surface plasmons at the sharp features of plasmonic antennas. While this eff…
Fabrication and micro-Raman spectroscopy of arrays of copper phthalocyanine molecular-magnet microdisks
Jiří Liška, Tomáš Krajňák, Peter Kepič +8
Phthalocyanines as organic semiconductors and molecular magnets provide plenty of industrial or high-tech applications from dyes and pigments up to gas sensors, molecular electroni…
Correlative electron and light spectroscopy of strongly-coupled mid-infrared plasmon and phonon polaritons
Pavel Gallina, Andrea Konečná, Jiří Liška +2
The ability to control and modify infrared excitations in condensed matter is of both fundamental and application interests. Here we explore a system supporting low-energy excitati…
