SILICON LIGHT EMITTING DEVICE

摘要

Provided is a highly-efficient silicon light emitting device including an improved structure by which more light of the light emitted toward the lateral side of the light emitting device is emitted toward the front side thereof than conventional light emitting devices so as to improve the brightness. The silicon light emitting device includes a substrate, a plurality of light emitting structures formed on the substrate, each of the light emitting structures comprising an active layer, and a metal electrode comprising a lower metal electrode formed below the substrate and an upper metal electrode formed on the light emitting structures. The light emitting structures have column shapes whose vertical cross-sections are inverse trapezoid.
