Wide bandgap semiconductors, made from such materials as GaN, SiC, diamond, and ZnSe, are undergoing a strong resurgence in recent years, principally because of their direct bandgaps, which give them a huge advantage over the indirect gap Sic As an example, more than 10 million blue LEDs using this technology are sold each month, and new, high brightness (15 lumens per watt), long-life white LEDs are under development with the potential to replace incandescent bulbs in many situations.  Meer
