| 发明名称 | Light-emitting devices on textured substrates | ||
| 摘要 | A device includes a textured substrate, which further includes a plurality of trenches. Each of the plurality of trenches includes a first sidewall and a second sidewall opposite the first sidewall. A plurality of reflectors configured to reflect light is formed, with each of the plurality of reflectors being on one of the first sidewalls of the plurality of trenches. The second sidewalls of the plurality of trenches are substantially free from any reflector. | ||
