WebThe compositions of SiOCs were controlled by adjusting the synthesis conditions (e.g., sweep gas and pyrolysis time) and C content of the SiOC precursors. The use of N2 sweep gas instead of H2/Ar suppressed the formation of SiC and Cfree. In addition, the amount of inactive SiO2 phase in SiOCs was further suppressed using a C-rich precursor. WebDec 11, 2024 · SiO gas was generated from pellets of a 1:2 molar ratio of SiC and silica (SiO2). The reactions were investigated through CO off-gas analysis in conjunction with …
WebDec 23, 2011 · We present tight-binding simulated annealing calculations, in order to construct models of SiC QDs in SiO 2, with the aim of obtaining an overview of the possible defects at the SiC/SiO 2 interface. We identify a number of recurring interface defects which can be attributed to C or Si rich conditions or general lattice mismatch relaxation.
