SEMICONDUCTOR LIGHTING DEVICE WITH A HIGH EFFICIENCY AND PHOTONIC BIOSENSOR USING THE SAME

摘要

PURPOSE: A high efficiency semiconductor light emitting device and a photonic bio sensor are provide to improve luminous efficiency by forming a transparent doping layer with multilayer structure on the upper side of a light emitting layer. CONSTITUTION: A semiconductor light emitting device includes a bottom electrode, a light emitting layer, and a top electrode. The light emitting layer includes a silicon nano crystal. A doping layer(200) with multilayer structure is formed on the upper side of the light emitting layer by alternatively growing thin films with different band gaps A hole injection layer is formed between the bottom electrode and the light emitting layer. A transparent conductive electrode(130) is formed on an electron injection layer(120).
