Carbide LED production before long stopped when a different material, gallium nitride, confirmed ten–a hundred times brighter emission. This difference in efficiency is as a result of unfavorable indirect bandgap of SiC, whereas GaN provides a direct bandgap which favors light emission. Cost and Scalability: While SiC gives superior performance, https://www.quora.com/profile/Trevor-Flatcher-2/Comparative-analysis-of-silicon-carbide-and-traditional-silicon-materials-Silicon-Carbide-vs-Traditional-Silicon-Mater
