摘要：
A light emitting device with reduced forward voltage Vf by utilizing the excellent lateral conduction of two-dimensional electron gas (2DEG) and two-dimensional hole gas (2DHG) structure and, more specifically, by improving the vertical conduction of 2DEG and 2DHG structure by means of vertical conductive passages formed in 2DEG and 2DHG structure. The conductive passages are formed via discontinuities in 2DEG and 2DHG structure. The discontinuities can be in the form of openings by etching 2DEG or 2DHG structure, or in the form of voids by growing 2DEG or 2DHG structure on a rough surface via epitaxy facet control. The discontinuities can be formed by vertical displacement of 2DEG structure. A method is provided for manufacturing a light emitting device with reduced forward voltage same.
