摘要: A semiconductor structure includes a light emitting region, a p-type region disposed on a first side of the light emitting region, and an n-type region disposed on a second side of the light emitting region. At least 10% of a thickness of the semiconductor structure on the first side of the light emitting region comprises indium. Some examples of such a semiconductor light emitting device may be formed by growing an n-type region, growing a p-type region, and growing a light emitting layer disposed between the n-type region and the p-type region. The difference in temperature between the growth temperature of a part of the n-type region and the growth temperature of a part of the p-type region is at least 140° C.

摘要: In some embodiments of the invention, a transparent substrate AlInGaP device includes an etch stop layer that may be less absorbing than a conventional etch stop layer. In some embodiments of the invention, a transparent substrate AlInGaP device includes a bonded interface that may be configured to give a lower forward voltage than a conventional bonded interface. Reducing the absorption and/or the forward voltage in a device may improve the efficiency of the device.
