Teos mechanism
Web1 Mar 2024 · The mechanisms of plasma-enhanced chemical vapor deposition using tetraethoxysilane (TEOS)-based plasma were investigated by monitoring the plasma via experimental and computational approaches using a quadrupole mass spectrometer/residual gas analyzer and coupled plasma-gas flow simulation. For … WebIn this work, we investigated the kinetic balance between ammonia-catalyzed hydrolysis of tetraethyl orthosilicate (TEOS) and subsequent condensation over the growth of silica particles in the Stber method. Our results reveal that, at the initial stage, the reaction is dictated by TEOS hydrolysis to form silanol monomers, which is denoted as ...
