Abstract :
Selective area growth of GaN nanocolumn arrays on Si substrates was developed. Orange-emitting nanocolumns on GaN/Al2O3 templates were optically characterized, fabricating red-color InGaN-based nanocolumn LEDs. Successful monolithic integration of four emission-colors nanocolumn LEDs was demonstrated.
