Landau level spectroscopy of BiTe
I. Mohelsky, A. Dubroka, J. Wyzula +9
Here we report on Landau level spectroscopy in magnetic fields up to 34 T performed on a thin film of topological insulator BiTe epitaxially grown on a BaF substrate. T…
Type-II InAs/GaAsSb/GaAs quantum dots as artificial quantum dot molecules
P. Klenovsky, V. Krapek, J. Humlicek
We have studied theoretically the type-II GaAsSb capped InAs quantum dots for two structures differing in the composition of the capping layer, being either (i) constant or (ii) wi…
Electronic structure of InAs quantum dots with GaAsSb strain reducing layer: Localization of holes and its effect on the optical properties
P. Klenovský, V. Křápek, D. Munzar +1
The electronic structure of InAs quantum dots covered with the GaAs(1-y)Sb(y) strain reducing layer has been studied using the k.p theory. We explain previous experimental observat…
Raman and infrared studies of La_1-ySr_yMn_1-xM_xO_3 (M=Cr, Co, Cu, Zn, Sc or Ga): Oxygen disorder and local vibrational modes
A. Dubroka, J. Humlicek, M. V. Abrashev +3
We present results of our study of polarized Raman scattering and infrared reflectivity of rhombohedral ceramic La_1-ySr_yMn_1-xM_xO_3 manganites in the temperature range between 7…
Interpretation of the in-plane infrared response of the high-Tc cuprate superconductors involving spin fluctuations revisited
Petr Casek, Christian Bernhard, Josef Humlicek +1
The in-plane infrared response of the high-Tc cuprate superconductors was studied using the spin-fermion model, where charged quasiparticles of the copper-oxygen planes are coupled…
Anomalous oxygen isotope effect on the in-plane FIR conductivity of detwinned YBa2Cu3O
C. Bernhard, T. Holden, A. V. Boris +6
We observe an anomalous oxygen isotope effect on the a-axis component of the far-infrared electronic response of detwinned YBa2Cu3O. For O a pronounced low…
