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…
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…
Polarization anisotropy of the emission from type-II quantum dots
P. Klenovsky, D. Hemzal, P. Steindl +3
We study the polarization response of the emission from type-II GaAsSb capped InAs quantum dots. The theoretical prediction based on the calculations of the overlap integrals of th…
Anomalies of the infrared-active phonons in underdoped YBCO as an evidence for the intra-bilayer Josephson effect
D. Munzar, C. Bernhard, A. Golnik +2
The spectra of the far-infrared c-axis conductivity of underdoped YBCO crystals exhibit dramatic changes of some of the phonon peaks when going from the normal to the superconducti…
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…
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…
