The aim of this paper is to consider optical and electrical properties of MOVPE GaN homostruture LEDs. The sample that has been selected for the study, doped with Si and Mg for n and p region of junction, respectively. The V-I and L-I characteristics of this device indicate that diffusion and space charge currents have the main role in luminescence, because in this current range defects levels ...
We make a comparative study of the luminescent properties of InGaP films grown on GaAs substrates by two different growth techniques: liquid phase epitaxy (LPE) and metal-organic vapor phase epitaxy (MOVPE). The grown InxGa1KxP (xz0.5) films were nearly lattice matched to GaAs and had the same thickness of approximately 0.5 mm. Photoluminescence (PL) measurements were performed in a wide temper...

The goal of the study is to compare quality of vapour phase reflowed solder joints soldered on different printed circuit board (PCB) surface finishes. Vapour phase reflow soldering guarantees the highest reliability, quality of processing and process safety. The big advantage of heat transfer in vapour phase soldering (VPS) is the extremely efficient transfer of latent heat through the condensi...
BACKGROUND Use of essential oils for controlling Candida albicans growth has gained significance due to the resistance acquired by pathogens towards a number of widely-used drugs. The aim of this study was to test the antifungal activity of selected essential oils against Candida albicans in liquid and vapour phase and to determine the chemical composition and mechanism of action of most potent...
