Abstract:
1. For use in conjunction with a light-emitting semiconductor structure that includes a semiconductor active region of a first conductivity type containing a quantum size region and having a first surface adjacent a semiconductor input region of a second conductivity type that is operative, upon application of electrical potentials with respect to said active and input regions, to produce light emission from said active region, a method for enhancing operation of said light-emitting semiconductor structure, comprising: providing a semiconductor output region that includes a semiconductor auxiliary layer of said first conductivity type adjacent a second surface, which opposes said first surface of said active region, and providing said auxiliary layer as comprising a semiconductor material having a diffusion length for minority carriers of said first conductivity type material that is substantially shorter than the diffusion length for minority carriers of the semiconductor material of said active region.
