Material of the month – silicon carbide | IOM3

This diode was made from silicon carbide, and his work led to the light emitting diode (LED). Although silicon carbide was experimented with to make early LEDs, it was soon replaced by gallium nitride (GaN), which gave much brighter light thanks to its direct bandgap, compared to SiC’s less efficient indirect bandgap.
