Giant dielectric permittivity in Nb-doped rutile crystals
D. Nuzhnyy, V. Bovtun, J. Petzelt +13
Dielectric properties of Nb-doped (~1.5 at%) rutile single crystals were studied in the 10-300 K temperature range (at frequencies below the MHz range down to 0.3 K) in a broad fre…
Ultrafast Terahertz Photoconductivity and Near-Field Imaging of Nanoscale Inhomogeneities in Multilayer Epitaxial Graphene Nanoribbons
Arvind Singh, Jan Kunc, Tinkara Troha +2
We study broadband terahertz (THz) conductivity and ultrafast photoconductivity spectra in lithographically fabricated multilayer epitaxial graphene nanoribbons grown on C- face of…
Spin-to-charge-current conversion in altermagnetic candidate RuO probed by terahertz emission spectroscopy
J. Jechumtál, O. Gueckstock, K. Jasenský +19
Using the THz emission spectroscopy, we investigate ultrafast spin-to-charge current conversion in epitaxial thin films of the altermagnetic candidate RuO. We perform a quantit…
Dynamics of local photoconductivity in GaAs and InP investigated by THz SNOM
Tinkara Troha, Arvind Singh, Petr Kužel +1
Terahertz scanning near-field optical microscope (THz-SNOM) is employed to measure ultrafast evolution of THz conductivity spectra after photoexcitation of GaAs and InP wafers usin…
Dimethylamino terminated ferroelectric nematogens revealing high permittivity
Martin Cigl, Natalia Podoliak, Tomáš Landovský +3
Since the recent discoveries, ferroelectric nematics became of upmost interest due to their outstanding ferroelectric properties. In this work, we prepared a series of polar molecu…
