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 …

Off-Axis Sputtering Deposition System for Growth of Single Crystalline Films
TS-015210 — This innovative deposition system is able to grow single crystalline films of a broad range of complex materials with unprecedented crystalline quality of binary, ternary and quaternary oxides and intermetallics with simple or complex crystal structures.
Sputter deposition is one of the dominant techniques used in manufacturing films and coatings in many industries. Conventional sputtering uses an “on-axis” geometry, i.e., the substrate directly faces the sputter target. Due to the energetic bombardment of sputtered atoms, sputtering i…
