초록
The luminous efficiency of a light-emitting diode-based semiconductor light source applied as a flexible display and lighting source is an essential characteristic. In order to improve luminous efficiency, various research methods, including light emitting and current injection layers, have been proposed. However, since this efficiency improvement is based on a planar structure, it is not easy to improve the optical properties. In this study, the nano-patterned column integrated structures were formed through the reactive etching process. In addition, a semiconductor light source having a light emitting structure by depositing multi-quantum healthy layers on the nano-sized column structure can be realized through the etched nano frame and hole structure.
