Micron scale ultra-low-cost light emitting diodes made using silicon carbide semiconductor material

A next generation of silicon-carbide (SiC) -based high performance microLEDs has the potential to replace existing gallium-indium nitride-based LED used in LED illuminated displays. The development of these SiC microLEDs is the goal of this research in collaboration with display company AVT Solutions Ltd. Silicon and carbide are low-cost earth-abundant minerals with ?1% of the cost of gallium nitride. This has the potential to dramatically increase market penetration of microLED-illuminated displays compared to current LED displays using gallium-indium nitride materials due to the dramatic cost improvement. The longer term goal is to demonstrate a high performance but very cost effective microLED displays of interest to AVT Solutions made of silicon carbide and to demonstrate that these microLEDs possess the optoelectronic characteristics suitable for display application including brightness, uniformity, and stability.
