摘要： Re-emitting semiconductor constructions (RSCs) for use with LEDs, and related devices, systems, and methods are disclosed. A method of fabrication includes providing a semiconductor substrate, forming on a first side of the substrate a semiconductor layer stack, attaching a carrier window to the stack, and removing the substrate after the attaching step. The stack includes an active region adapted to convert light at a first wavelength λ1 to visible light at a second wavelength λ2, the active region including at least a first potential well. The attaching step is carried out such that the stack is disposed between the substrate and the carrier window, which is transparent to the second wavelength λ2. The carrier window may also have a lateral dimension greater than that of the stack. The removal step is carried out so as to provide an RSC carrier device that includes the carrier window and the stack.

摘要： A pixelated light emitting diode (LED) and a method for pixelating an LED are described. The pixelated LED includes two or more monolithically integrated electroluminescent elements disposed adjacent each other on a substrate, wherein at least a portion of each electroluminescent element immediately adjacent the substrate includes an inverted truncated pyramidal shape. The method for pixelating an LED includes selectively removing material from the major surface of an LED to a depth below the emissive region, thereby forming an array of inverted truncated pyramid shapes. The efficiency of the pixelated LEDs can be improved by incorporating the truncated pyramidal shape. Additionally, the crosstalk between adjacent LED pixels can be reduced by incorporating the truncated pyramidal shape.

摘要： A stack of semiconductor layers (310) forms a re-emitting semiconductor construction (RSC). The stack (310) includes an active region (316) that converts light at a first wavelength to light at a second wavelength, the active region (316) including at least one potential well. The stack (310) also includes an inactive region (318) extending from an outer surface of the stack to the active region. Depressions (326) are formed in the stack (310) that extend from the outer surface into the inactive region (318). An average depression depth is at least 50% of a thickness of the inactive region. Alternatively, the average depression depth is at least 50% of a nearest potential well distance. Still other alternative characterizations of the depressions (326) are also disclosed. The depressions (326) may have at least a 40% packing density in plan view. The depressions (326) may also have a substantial portion of their projected surface area associated with obliquely inclined surfaces.
