| Outline of Final Research Achievements |
The theory of polarization engineering was applied into the design of device structure of InGaN/GaN LED. At the end of the project, new device processing and epitaxial structure for long wavelength LED was developed.
|
| Academic Significance and Societal Importance of the Research Achievements |
This research propose a novel device structure with advanced device theory toward the issue of developing high efficiency red and yellow InGaN/GaN LED.
The research has great potential in overcome the basic problem of InGaN/GaN LED to mitigate "the green gap".
