Abstract:
Disclosed herein are multi-layered optically active regions for semiconductor light-emitting devices (LEDs) that incorporate intermediate carrier blocking layers, the intermediate carrier blocking layers having design parameters for compositions and doping levels selected to provide efficient control over the carrier injection distribution across the active regions to achieve desired device injection characteristics. Examples of embodiments discussed herein include, among others: a multiple-quantum-well variable-color LED operating in visible optical range with full coverage of RGB gamut, a multiple-quantum-well variable-color LED operating in visible optical range with an extended color gamut beyond standard RGB gamut, a multiple-quantum-well light-white emitting LED with variable color temperature, and a multiple-quantum-well LED with uniformly populated active layers.

Claim (Index 1):
A multi-layer semiconductor light emitting structure comprising:\n a first quantum confinement structure for emitting light of a first wavelength; a first intermediate carrier blocking layer; a second quantum confinement structure for emitting light of a second wavelength, wherein the first intermediate carrier blocking layer is disposed between the first quantum confinement structure and the second quantum confinement structure and the first intermediate carrier blocking layer comprises a composition that is undoped or doped of a single conductivity type to provide a first predetermined band-gap and band-offsets relative to each of the first quantum confinement structure and the second quantum confinement structure; a second intermediate carrier blocking layer ; a third quantum confinement structure for emitting light of a third wavelength, wherein the second intermediate carrier blocking layer is disposed between the second quantum confinement structure and the third quantum confinement structure and the second intermediate carrier blocking layer comprises a composition that is undoped or doped of a single conductivity type to provide a second predetermined band-gap and band-offsets relative to each of the second quantum confinement structure and the third quantum confinement structure; and the first, second and third quantum confinement structures emitting primary colors of red, green and blue respectively, wherein the band-gaps and the band-offsets of the first and second intermediate carrier blocking layers are selected to cause the first, second and third quantum confinement structures to emit light of the respective wavelength and with a relative intensity contribution to cause the multi-layer semiconductor light emitting structure to emit white light.
