Light emitting device, production method thereof, and light emitting apparatus and display unit using the same
An n-type cladding layer formed of a non-single crystal body of n-type AlGaN, a light emitting layer containing a plurality of micro-crystals made from ZnO, and a p-type cladding layer formed of a non-single crystal body of p-type BN are sequentially stacked on a substrate made from quartz glass. An insulating layer is formed between the n-type cladding layer and the p-type cladding layer in such a manner as to bury spaces between the micro-crystals, to thereby prevent occurrence of leakage current. The insulating layer is formed by oxidizing the surface of the n-type cladding layer. Since the light emitting layer contains the plurality of micro-crystals improved in crystallinity, it is possible to enhance the emission efficiency, to extend the selection range of each of materials for forming the light emitting layer, n-type cladding layer, p-type cladding layer, and substrate, and to form a device array on a common substrate having a large area.
