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…
Tunable terahertz oscillations in superlattices subject to an in-plane magnetic field
M. Orlita, R. Grill, L. Smrcka +1
We present a concept of terahertz oscillations in superlattices that are generated under conditions apparently different from standard Bloch oscillations. These oscillations are in…
