Quantum Well Design for Red-Emitting InGaN LEDs
TS-042441 — The quantum well design is incorporated within a red-emitting InGaN QW LED, an LED type that usually cannot efficiently emit wavelengths larger than blue/green. The LED can be incorporated into a same-material RGB platform for white LEDs, because the well design increases efficiency and decreases indium composition compared to similar wavelength InGaN LEDs.
Blue-emitting InGaN quantum well (QW) LEDs now have 69% external quantum efficiency, but increasing the emitted-wavelength decreases the efficiency significantly. The inversion asymmetry of the InGaN lattice increases the induced strain, which in turn increases the piezoelectric effect. Charge bui…

Efficient Graded III-Nitride Nanowires
TS-014952 — A nanowire that overcomes defect formation normally found in LEDs, leading to higher charge density.
Unlike traditional light bulbs, Light Emitting Diodes (LEDs) use less power, last longer, and contain no environmentally harmful substances. However, LEDs struggle with technical errors, such as lattice mismatch and large resistances. As adoption increases, it is necessary to develop LEDs that are…

Head and Gaze Tracking Device for Baseball Training
TS-014762 — A software system optimizing head and eye movement tracking for baseball, softball, tennis, and more
In the game of baseball, pitches can reach 90 mph or higher; at this rate the ball will cross the plate in roughly 420 milliseconds. The batter will have 220-260 milliseconds to track the ball with their gaze before having to swing the bat. Hence the piece of advice; “keep your eye on the ba…
