Correlative Imaging of Individual CsPbBr3 Nanocrystals: Role of Isolated Grains in Photoluminescence of Perovskite Polycrystalline Thin Films
Petr Liška, Tomáš Musálek, Tomáš Šamořil +12
We report on the optical properties of CsPbBr3 polycrystalline thin film on a single grain level. A sample comprised of isolated nanocrystals (NCs) mimicking the properties of the…
Phase-resolved optical characterization of nanoscale spin waves
Ondřej Wojewoda, Martin Hrtoň, Meena Dhankhar +7
We study theoretically and experimentally the process of Brillouin light scattering on an array of silicon disks on a thin Permalloy layer. We show that phase-resolved Brillouin li…
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…
Strong coupling in a Au plasmonic antenna-SiO layer system: a hybrid mode analysis
Pavel Gallina, Michal Kvapil, Jiří Liška +5
A detailed analysis of the optical response of a system accommodating several coupled modes is needed for the complete understanding of the strong coupling effect. In this paper, w…
