Carbide LED production soon stopped when a different material, gallium nitride, confirmed 10–one hundred times brighter emission. This difference in efficiency is as a result of unfavorable indirect bandgap of SiC, whereas GaN features a direct bandgap which favors light emission. Cost and Scalability: Although SiC provides superior performance, its https://www.quora.com/profile/Trevor-Flatcher-2/The-Versatile-Applications-of-Silicon-Carbide-Special-Ceramics-in-Modern-Industries-Silicon-carbide-SiC-special-ceram
