The thermal … WebMay 10, 2024 · The morphology of the SiC/SiOx heterojunctions was that of neck-like nanochains, and the diameter of the SiOx bean was 2–6 μm. As reported in previous studies, the size of the SiOx bean was about 50 nm after firing at 1500 °C [9,14,16]. Why were the morphologies of the SiC/SiOx heterojunctions so different after firing at a different ...
WebNovel 2-D nanoscale SiC networks have been generated by heating SiC–Fe–Co mixtures under a CO atmosphere. Examination of the products by EDX and HRTEM showed that most of the nanowires consist of β-SiC elongated single crystals, wrapped in amorphous SiOx sheaths. Intriguing crystalline features and defects associated with SiC nanowires were … WebThe SiC/SiOx hetero-superlattice (HSL) consisting of alternating near-stoichiometric SiC barrier layers for the electrical transport and silicon rich SiOx matrix layers for the quantum dot formation is a promising approach to the realization of silicon quantum dot (Si–QD) absorbers for 3rd generation solar cells.
