Abstract: One or more regions of graded composition are included in a III-P light emitting device, to reduce the Vf associated with interfaces in the device. In accordance with embodiments of the invention, a semiconductor structure comprises a III-P light emitting layer disposed between an n-type region and a p-type region. A graded region is disposed between the p-type region and a GaP window layer. The aluminum composition is graded in the graded region. The graded region may have a thickness of at least 150 nm. In some embodiments, in addition to or instead of a graded region between the p-type region and the GaP window layer, the aluminum composition is graded in a graded region disposed between an etch stop layer and the n-type region.

Abstract: A light emitting device and a method of increasing the light output of the device utilize a chirped multi-well active region to increase the probability of radiative recombination of electrons and holes within the light emitting active layers of the active region by altering the electron and hole distribution profiles within the light emitting active layers of the active region (i.e., across the active region). The chirped multi-well active region produces a higher and more uniform distribution of electrons and holes throughout the active region of the device by substantially offsetting carrier diffusion effects caused by differences in electron and hole mobility by using complementary differences in layer thickness and/or layer composition within the active region.

Abstract: An LED and a method of fabricating the LED which utilize controlled oxygen (O) doping to form at least one layer of the LED having an O dopant concentration which is correlated to the dominant emission wavelength of the LED. The O dopant concentration is regulated to be higher when the LED has been configured to have a longer dominant emission wavelength. Since the dominant emission wavelength is dependent on the composition of the active layer(s) of the LED, the O dopant concentration in the layer is related to the composition of the active layer(s). The controlled O doping improves the reliability while minimizing any light output penalty due to the introduction of O dopants. In an exemplary embodiment, the LED is an AlGaInP LED that includes a substrate, an optional distributed Bragg reflector layer, an n-type confining layer, an optional n-type set-back layer, an active region, an optional p-type set-back layer, a p-type confining layer and an optional window layer.
