LIGHT EMITTING DEVICE

摘要

PURPOSE: A light emitting element is provided to prevent the internal quantum efficiency from being reduced due to crystalline defects by including a carrier trapping part in at least one layer of a multiple quantum well structure. CONSTITUTION: A buffer layer(13) is formed on a substrate(11). A first semiconductor layer(15) is formed on the buffer layer. A second semiconductor layer(19) is formed on the first semiconductor layer. A multiple quantum well structure(17) including a well layer(17b) and a barrier layer(17a) is interposed between the first semiconductor layer and the second semiconductor layer. At least one carrier trapping part is formed in at least one layer of the multiple quantum well structure.
