Researchers Grow GaN MicroLED Arrays on a Flexible Graphene Substrate

Researchers from Korea's Seoul National University and Sungkyunkwan University recently developed a method to grow GaN LED arrays on a flexible graphene layer.

The so-called microdisk arrays exhibit excellent crystallinity with a uniform in-plane orientation and strong blue light emission.

The researchers grew the GaN microdisks on a graphene layer (grown on a sapphire substrate) covered with a micro-patterned SiO2 mask using metal–organic vapor-phase epitaxy.

The microdisks were then processed into micro-LEDs and then successfully transferred onto bendable substrates.

The research demonstrated it is possible to grow high quality LEDs on graphene and then integrate it into flexible microLED devices.
