Light emitter with a conductive transparent p-type layer structure

摘要

A light emitting device includes an n-type layer, a p-type layer structure, a layer of p-type nano-dots imbedded in the p-type layer structure, and an active region sandwiched between the n-type layer and the p-type layer structure, where the p-type nano-dots possess a sheet density of 1010 to 1012 cm−2, a lateral dimension of 2-20 nm, and a vertical dimension of 1-5 nm. The p-type layer structure with a layer of p-type nano-dots imbedded therein provides good vertical conductivity and UV transparency. Also provided is a method for making the light emitting device.
