Carbide LED production soon stopped when a different material, gallium nitride, showed ten–100 times brighter emission. This difference in efficiency is mainly because of the unfavorable indirect bandgap of SiC, whereas GaN incorporates a direct bandgap which favors light emission. The earliest electrical application of SiC was being a surge https://www.facebook.com/permalink.php?story_fbid=pfbid0XCoAmB3YxUyYH1ZgbMmeT1UD412oN5SCiaH3icApCTbHUPpxph3pSLpTYiNaou5Gl&id=61562415773754&__cft__[0]=AZUZnWm-5_LaeZLgoUSJ6OdwTUBoAeV5ZGhyyo_pcT8Y2ciNGkEb7aB-tYl3TR_qOy2k7XP9wP-TXDwbeCPuBRLPb5i8Hi2yCVsL9I5DnH_D159R2ypfQ4Gv2lXHWrg-9EKaZUJBYcP5XbS8XfJAX0YHa4n31eYgaAl3Ju0QWFIGmHvvfcCUa0DPPrvCcA4SU0rLKTA0oIV1XP635km24GXV&__tn__=%2CO%2CP-R
