23_40/2011Flexible Optoelectronics: Flexible Inorganic Nanostructure Light-Emitting Diodes Fabricated on Graphene Films (Adv. Mater. 40/2011)

Inorganic-based flexible light-emitting diodes (LEDs) using single-crystalline GaN/ZnO coaxial nanorod heterostructures grown directly on large graphene films are reported on page 4614 by Gyu-Chul Yi and co-workers. The LEDs demon-strate reliable operation in a flexible form, with no significant degradation in their electroluminescent or electrical characteristics. This approach provides a general and rational route to develop many different inorganic optoelectronics in flexible or stretchable forms.
