GaN-Ready Aluminum Nitride Substrates

The objective of this project was to develop and then demonstrate the efficacy of a cost-effective approach for a low-defect-density substrate on which aluminum indium gallium nitride (AlInGaN) light-emitting diodes (LEDs) can be fabricated. The efficacy of this GaN-ready substrate would then be tested by growing high-efficiency, long-lifetime InxGa1-xN blue LEDs.

LED Display Engineering

The primary objective of this project was to develop and implement a method that compensates for the inefficiency of the green light-emitting diode (LED). The proposed engineering solution was to use RGBW combination in every pixel to save energy. A 32" x 16" display with pixel spacing of one inch, which is usually used for outdoor applications, was built.

Self-Activating and Doped Tantalate Phosphors

Phosphors are useful in numerous applications including lighting. Tantalates are very promising materials because they are especially robust and resistant to chemical degradation. Studies have shown that rare-earth tantalates are excellent host lattices for europium (Eu)-doped red-emitting phosphors, excited by blue light.
