ACCOMPLISHMENTS
- Discovered a stable cubic phase of GaS that could passivate the surface of GaAs solar cells, other optoelectronic and microelectronic devices
- Developed techniques for determining surface passivation
- Developed new passivation technology
|
COMMERCIALIZATION
- This passivation technology is used in all cell phones
- TRI-QUINT, a manufacturer of microelectronic and optoelectronic devices, purchased GALLIA, Inc. and the passivation technology. The passivation technology was used to improve their GaAs discrete devices
|
GOVERNMENT/SCIENCE APPLICATIONS
- It is used or can be used on solar cells and other
GaAs devices for many NASA missions
- NASA and the Military benefits by increases in “End of Life” efficiency and reliability with this technology
