Microsecond Bias Polarity Switching Reveals Hidden Charge Dynamics at Halide Perovskite Interfaces
Marián Betušiak, Roman Grill, Eduard Belas +6
We present a time-domain technique based on rapid bias polarity switching (BiPS) to probe charge transport and near-surface defects in halide perovskite single crystals. The method…
Space charge limited photocurrents and transient currents in CdZnTe radiation detectors
Katarina Ridzonova, Eduard Belas, Roman Grill +2
We combined steady-state photoconductivity and laser-induced transient current measurements under above-band-gap illumination to study the space charge formation in CdZnTe. Analyti…
Electrical and Spectroscopic Properties of SiC Detectors
Mykola Brynza, Eduard Belas, Petr Praus +2
In this paper we compare suitability of three different semi-insulating bulk silicon carbide (SiC) materials for fabrication of radiation detectors. We prepared planar sensors with…
Space charge formation in chromium compensated GaAs radiation detectors
E. Belas, R. Grill, J. Pipek +7
Space charge formation in chromium-compensated GaAs sensors is investigated by the laser-induced transient current technique applying pulsed and DC bias. Formation of non-standard…
Deep Levels and Mixed Conductivity in Organometallic Halide Perovskites
Artem Musiienko, Pavel Moravec, Roman Grill +10
Understanding the type, formation energy and capture cross section of defects is one of the challenges in the field of organometallic halide perovskite (OMHP) devices. Currently, s…
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…
Systematic investigation of influence of n-type doping on electron spin dephasing in CdTe
D. Sprinzl, P. Horodyska, E. Belas +3
We used time-resolved Kerr rotation technique to study the electron spin coherence in a comprehensive set of bulk CdTe samples with various concentrations of electrons that were su…
