Abstract
The purpose of the present invention is to provide a method for manufacturing a light-amplified optoelectronic in device, on which pristine or doped graphene is transferred. Specifically, the method includes the steps of: depositing a first electrode, as a thin film, on the light emitting device; transferring pristine or doped graphene on the electrode thin film; etching the light emitting device in contact with the electrode thin film on which the transferred graphene has been transferred, thereby removing a part of the electrode thereon; spin-coating photoresist on the etched light emitting device; removing the photoresist from the spin-coated light emitting device, thereby forming an electrode thin film in a spin form and the pristine transferred to or graphene doped to the electrode thin film; and depositing metal on a second electrode.
