LIGHT EMITTING DEVICE, A LIGHT EMITTING DEVICE PACKAGE, A LIGHTING SYSTEM, AND A METHOD FOR FABRICATING THE LIGHT EMITTING DEVICE CAPABLE OF IMPROVING LUMINOUS EFFICIENCY

摘要

PURPOSE: A light emitting device, a light emitting device package, a lighting system, and a method for fabricating the light emitting device are provided to improve luminous efficiency by using an InN layer.;CONSTITUTION: A first light emitting structure(10) is formed on a growth substrate(5). A first light emitting structure comprises a semiconductor layer(11) of a first conductivity type, an active layer(12), and a second semiconductor layer(13) of a second conductivity type. An InN layer(20) is formed on the second semiconductor layer. A transparent conductive oxide layer(30) touches the InN layer. A first electrode(40) is electrically connected to the semiconductor layer. A second electrode(50) is electrically connected to the transparent conductive oxide layer.;COPYRIGHT KIPO 2013
