Frequently Asked Questions:

What is the MURI?

This MURI program consists of investigators at North Carolina State University, University of California-Santa Barbara, Rensselaer Polytechnic Institute, and University of California-San Diego concerned with the theoretical and experimental application of wurtzite wide band gap (WBG) semiconductors in efficient power switching devices.

What are the MURI Objectives?

- Theoretical and experimental investigations regarding carrier dynamics along selected crystallographic directions under high and very high electric fields in wurtzite wide band gap (WBG) semiconductors.

- Conventional and lateral epitaxial overgrowth of GaN and AlGaN on SiC substrates.

- Chemical preparation and fusion of optimally oriented surfaces of GaN and AlGaN on SiC substrates.

- Fabrication of heterostructure devices for miniature power supplies.

- Identify fundamental mechanisms and quantify lifetime and mean free path of electrons under various applied voltages in III-Nitride and SiC materials.

- Determine limits of charge carrier transport in vertically structured devices.

- Employ above information for theoretical and the experimental design and fabrication of heterostructure devices with ballistic mobilities for efficient power switching and actuator control.
