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. WebLow-temperature as well as the transfer free graphene growth on substrates is the major concern of graphene research for its practical applications. The transfer free graphene growth on SiO2 covered Si (SiO2/Si) substrate at 250 °C based on a solid-liquid-solid reaction has been achieved by tin. Sodium ethoxide pyrolysis
WebThe growth of nitride on large-size and low-cost amorphous substrates has attracted considerable attention for applications in large-scale optoelectronic devices. In this paper, we reported the growth of GaN-based light-emitting diodes (LEDs) on amorphous SiO2 substrate with the use of nanorods and graphene buffer layers by metal organic chemical … Weband SiC reacted mainly with MnO in slag to produce gas. Although the dissolution behavior of SiC in CaO–SiO 2– MnO slag had been studied, there is no research on the reaction …
WebApr 15, 2024 · Fig. 1 (b) displays the Eox of SiO 2 film and the Φb of SiC/SiO 2 interface for various samples. Compared with the #AO sample, the Eox and Φb of all re-oxidized samples are improved. Among the four re-oxidized samples, the #O3P sample has the largest Eox and Φb values, which are 12.18 MV/cm and 2.63 eV, respectively. WebAn (α-Al 2 O 3 + Si)/Al composite was fabricated by an in situ process called exothermic dispersive synthesis from a powder blend of Al and SiO 2.The synthesis mechanism and resulting microstructure of the composite were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and X-ray …
