WebWe report the effects of thermal oxidation on the sensing properties of porous silicon. Porous silicon substrates were prepared by electrochemical etching and thermally oxidized at different temperatures. A comparative EDS analysis shows that porous surfaces oxidized at higher temperatures have higher oxygen-to-silicon ratios. Our results indicate that the … WebFeb 13, 2024 · Since carbon is more electronegative than hydrogen the C-H bond is polarized towards carbon resulting in a more protic hydrogen (Figure 7.9. 2 a). In contrast, the lower electronegativity of silicon results in a more hydridic hydrogen (Figure 7.9. 2 b). This difference is reflected in the reaction chemistry of SiH 4 versus CH 4.
