LIGHT EMITTING DEVICE

摘要

PURPOSE: A light emitting device is provided to improve epitaxial quality by reducing an internal field due to a polarization difference between a quantum layer and an electron blocking layer. CONSTITUTION: An active layer(131) is arranged on a first conductive semiconductor layer(121). The active layer includes a quantum well layer and a plurality of quantum barrier layers. A second conductive semiconductor layer(147) is arranged on an electron blocking layer(145). A second conductive buffer layer(141) is arranged between the active layer and the electron blocking layer. A dopant layer(143) is arranged between the second conductive buffer layer and the electron blocking layer.
