Carbide LED production quickly stopped when a different material, gallium nitride, confirmed ten–a hundred times brighter emission. This difference in efficiency is due to unfavorable indirect bandgap of SiC, whereas GaN has a direct bandgap which favors light emission. [forty seven] Improved fracture toughness in SiC armor could be facilitated https://www.quora.com/profile/Trevor-Flatcher-2/The-Versatile-Applications-of-Silicon-Carbide-Special-Ceramics-in-Modern-Industries-Silicon-carbide-SiC-special-ceram
