SURFACE STRUCTURED LIGHT-EMITTING DIODE WITH IMPROVED CURRENT COUPLING |
摘要 |
<p>Structured-surface light-emitting diode having a light generating layer and a relatively thick, transparent current-spreading layer, vertical structuring of the top surface of the current-spreading layer serves to improve the decoupling of light, while at the same time, a second electrical contact layer with a distributed, lateral structure operates to achieve substantially uniform coupling of electrical current into the current-spreading layer.</p> |
