Radiation-emitting semiconductor chip with a radiation-emitting active layer |
摘要 |
Recesses interrupt an active layer on a semiconductor chip to improve the coupling out of light. As a result, side faces of the active layer appear, as seen from a light-generating point, at a large solid angle and the paths of light in the active layer are shortened.
