Abstract
In this work a synthesis of two-dimensional graphene related materials (GRM) in microwave plasma torch (MPT) discharge was studied. The MPT discharge operates at atmospheric pressure conditions in argon atmosphere. The discharge was driven by a microwave generator set to standard frequency of 2.45 GHz. Liquid ethanol vapours were led to the discharge by carrying gas - argon, was selected as a precursor. Decomposition of ethanol, at specific deposition conditions, led to synthesis of graphene flakes. Created samples were analysed using Raman spectroscopy and electron microscopy. The discharge was examined by optical emission spectroscopy.
Abstract (in Czech)
V této práci byla studována syntéza dvojrozměrných, grafenu podobných struktur v mikrovlnném plazmovém hořáku (MPT). MPT pracuje při atmosférickém tlaku v argonové atmosféře. Výboj byl buzen mikrovlnným generátorem, který pracuje na standardní frekvenci 2,45 GHz. Jako prekurzor byl vybrán kapalný ethanol, kterého páry byly vedeny argonem do oblasti výboje. Rozklad ethanolu, za určitých depozičních podmínek, vedl k syntéze grafenovych šupin. Vytvořené vzorky byly analyzovány s použitím Ramanovy spektroskopie a elektronové mikroskopie. Výboj byl zkoumán pomocí optické emisní spektroskopie.
