EN In this study we present the results of investigations on Schottky Au–GaN diodes by means of conventional DLTS and Laplace DLTS methods within the temperature range of 77 – 350 K. Si-doped GaN layers were grown by Molecular Beam Epitaxy technique (MBE) on sapphire substrates. DLTS signal spectra rev[...]

EN Semiconductor low-dimensional structures of CdTe quantum dots (QDs) embedded in ZnTe matrix have been investigated by micro-Raman spectroscopy. A reference ZnTe sample (without dots) was also studied for comparison. Both samples were grown by a molecular beam epitaxy technique on the p-type GaAs sub[...]

EN The n-type ZnO layers were grown by ALD method on p-type CdTe substrate. I-V characteristics verified rectifying properties of the test ZnO/CdTe solar cell diode and exhibited photovoltaic effect when the junction was exposed to light. The series resistance of the diode, determined from the I-V curv[...]

EN In this paper we report on the optical and electrical studies of single GaAs1-xNx epitaxial layers grown on GaAs substrates by means of atmospheric pressure metal organic vapour phase epitaxy (APMOVPE). Three kinds of samples with 1.2 %, 1.6 % and 2.7 % nitrogen content were studied. Optical propert[...]
