Coexisting phases of individual VO nanoparticles for multilevel nanoscale memory
Peter KepiÄ, Michal Horák, JiÅà 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…
Efficient nanoscale imaging of solid-state phase transitions by transmission electron microscopy demonstrated on vanadium dioxide nanoparticles
Michal Horák, Peter KepiÄ, JiÅà 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 KÅápek, Rostislav Åepa, 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…
Influence of deposition parameters on the plasmonic properties of gold nanoantennas fabricated by focused ion beam lithography
Michael Foltýn, Marek PatoÄka, Rostislav Åepa +2
The behavior of plasmonic antennas is influenced by a variety of factors, including their size, shape, and material. Even minor changes in the deposition parameters during the thin…
