GaN microrods on graphene substrates enable bendable optoelectronics devices

摘要

"Bendy" light-emitting diode (LED) displays and solar cells crafted with inorganic compound semiconductor microrods are moving one step closer to reality, thanks to graphene and the work of a team of researchers at Seoul National University (SNU). While most flexible electronics and optoelectronics devices are fabricated using organic materials, inorganic compound semiconductors such as GaN can provide further advantages, including superior optical, electrical, and mechanical properties. One major obstacle to their use, however, is the difficulty of growing them on flexible substrates.
