Morphology and Optical Properties of Thin Cd3As2 Films of a Dirac Semimetal Compound
Natalia Kovaleva, Ladislav Fekete, Dagmar Chvostova +1
Using atomic-force microscopy (AFM) and wide-band (0.02-8.5 eV) spectroscopic ellipsometry techniques we investigated morphology and optical properties of Cd3As2 films grown by non…
Bi layer properties in the Bi-FeNi GMR-type structures probed by spectroscopic ellipsometry
Natalia Kovaleva, Dagmar Chvostova, Ladislav Fekete +1
Bismuth (Bi) having a large atomic number is characterized by the strong spin-orbit coupling (SOC) and is a parent compound of many 3D topological insulators (TIs). The ultrathin B…
Bismuth layer properties in the ultrathin Bi-FeNi multilayer films probed by spectroscopic ellipsometry
N. N. Kovaleva, D. Chvostova, O. Pacherova +6
Using wide-band (0.5-6.5 eV) spectroscopic ellipsometry we study ultrathin [Bi(0.6-2.5 nm)-FeNi(0.8,1.2 nm)]N multilayer films grown by rf sputtering deposition, where the FeNi lay…
Twist-grain boundary phase characterized by AFM technique
Vladimira Novotna, Lubor Lejcek, Ladislav Fekete
Twist grain boundary (TGB) phases represent liquid crystalline systems with a regular array of defects. In our research, we studied a compound with a stable TGBC phase and establis…
Organic nanotubes created from mesogenic derivatives
Vladimira Novotna, Vera Hamplova, Lubor Lejcek +7
A facile route to prepare the nanotubes from rod-like mesogens dissolved in typical organic solvents is reported. For selected types of chiral rod-like molecules, both enantiomers…
Local moment formation and magnetic coupling of Mn guest atoms in BiSe: a low-temperature ferromagnetic resonance study
D. Savchenko, R. Tarasenko, M. Vališka +7
We compare the magnetic and electronic configuration of single Mn atoms in molecular beam epitaxy (MBE) grown BiSe thin films, focusing on electron paramagnetic (ferromagne…
