High Efficiency GaN-based Light Emitting Diodes with Embedded Air Voids/SiO2 Nanomasks

Not Accessible

Your library or personal account may give you access


We fabricated high efficiency LEDs with embedded micro-scale air voids and SiO2 nanomask exhibit smaller reverse-bias current and great enhancement of the light output (65% at 20mA) compared with the conventional LEDs.
