Investigation of internal electric fields in graphene/6H-SiC under illumination by Pockels effect
Vaclav Dedic, Jakub Sanitrak, Tomas Fridrisek +4
In this paper, we introduce a method for mapping profiles of internal electric fields in birefringent crystals based on the electro-optic Pockels effect and measuring phase differe…
Optical, magneto-optical properties and fiber-drawing ability of tellurite glasses in the TeO2-ZnO-BaO ternary system
J. Hrabovsky, L. Strizik, F. Desevedavy +11
The presented work is focused on the optical and magneto-optical characterization of TeO2-ZnO-BaO (TZB) tellurite glasses. We investigated the refractive index and extinction coeff…
Plasmon-plasmon interaction and the role of buffer in epitaxial graphene micro-flakes
Mykhailo Shestopalov, Václav Dědič, Martin Rejhon +7
We investigate the origin of the translational symmetry breaking in epitaxially grown single-layer graphene. Despite the surface morphology of homogeneous graphene films influenced…
Spectral Current Density and Responsivity Scaling for Fourier Transform Photocurrent Spectroscopy
Jan Kunc, Bohdan Morzhuk, Mykhailo Shestopalov +2
We propose and experimentally verify two methods to scale arbitrary units to photocurrent spectral density (A/eV) in Fourier Transform Photocurrent (FTPC) spectroscopy. We also pro…
Sub-surface alteration and related change in reflectance spectra of space-weathered materials
K. Chrbolková, P. Halodová, T. Kohout +7
One of the main complications for the interpretation of reflectance spectra of airless planetary bodies is surface alteration by space weathering caused by irradiation by solar win…
Influence of deep levels on the electrical transport properties of CdZnTeSe detectors
M Rejhon, J Franc, V Dědič +4
We investigated the influence of deep levels on the electrical transport properties of CdZnTeSe radiation detectors by comparing experimental data with numerical simulations based…
Investigation of deep levels in CdZnTeSe crystal and their effect on the internal electric field of CdZnTeSe gamma-ray detector
M Rejhon, V Dědič, L Beran +3
We present a study of deep levels in CdZnTeSe radiation-detection materials. The approach relies on electrical methods that combine time and temperature evolution of the electric f…
The electroluminescent properties based on bias polarity of the epitaxial graphene/aluminium SiC junction
M. Rejhon, J. Franc, V. Dědič +2
We investigated the electroluminescent properties of the epitaxial graphene/SiC junction. The temperature and current dependence of electroluminescence from the epitaxial graphene/…
Efficient Charge Collection in Coplanar Grid Radiation Detectors
Jan Kunc, Petr Praus, Eduard Belas +3
We have modeled laser-induced transient current waveforms in radiation coplanar grid detectors. Poisson's equation has been solved by finite element method and currents induced by…
Effect of residual gas composition on epitaxial graphene growth on SiC
Jan Kunc, Martin Rejhon, Eduard Belas +3
In recent years, graphene growth optimization has been one of the key routes towards large-scale, high-quality graphene production. We have measured in-situ residual gas content du…
