High Efficiency LED Designs Using Quantum Well Engineering
TS-057127 — Achieving high efficiency LEDs with green, amber and longer wavelengths using III-nitride/II-IV-nitride heterostructures as the active media.
Although extensive research and development over the past two decades has resulted in close to 100% external quantum efficiency (EQE) of InGaN based blue light emitting devices, efficiency of the longer visible wavelength emitting devices has remained relatively low. Spontaneous polarization origi…

Method to enhance light extraction efficiency in tunnel-injected III-Nitrate ultraviolet LEDs
TS-037365 — A novel method to enhance the transverse-electric and transverse-magnetic polarized light via relfective surfaces on top of a tunnel junction based LED structure.
III-Nitride ultraviolet light emitting diodes (UV LEDs) have a variety of promising applications, including sterilization and water purification. Currently, UV LEDs use an absorbing p-GaN top layer for hole injection, which reduces light extraction efficiency to lower than 20%. UV light emissions …
