Carbide LED production before long stopped when a different material, gallium nitride, showed 10–one 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. Cost and Scalability: When SiC offers superior performance, its production https://www.facebook.com/permalink.php?story_fbid=pfbid02s9f9Lp41k8PnY49Uufb4L6amB3fXhAKpPofyA5sxzVAWk7La5N1bvWCUq3vvWduKl&id=61562415773754&__cft__[0]=AZUQSxu7Y-sROKbsovm5AM1_3WrGcZqDRm5hctvbEhuke--Oe8MEVyImDqQHytMUn9zrhrB-KA5WuxRhWTiQL1HP6k_6omo-OkEX_Les9Ok9rDH0UbvK_TXiYqTGLHbVxfKnnOs9gK1pSuwbS32TiFqxJqR0Jv7PDiBET_FylQExJAyG5IVll6Bj5KqMf6oc1w5PNrniYU1ZoSjXjJPw22qy&__tn__=%2CO%2CP-R
