Summary

This course covers advanced topics on compound semiconductors (lll-Nitrides) and their heterostructures, from both physics and engineering perspectives, to explain the principles of some of the widespread electronic and optoelectronic devices used in our lives (LEDs, lasers, HEMTS, and power FETS).

Content

1. lntroduction
2. Background physics: From crystal to band structure
3. Heterojunctions/heterostructures: Brief introduction to band alignment, Quantum Wells, Quantum Dots.
4. Case of lll-Nitride semiconductors: Polarization fields
5. Epitaxial Growth: how these structures are grown in practice
6.Optoelectronic devices
7. Advanced device concepts: recent advances in the literature in GaN optoelectronics (state of the art, micro LEDs, deep UV LEDs' long
wavelength LEDs, VCSELS etc..)
8. Electronic Devices
9. Radio frequency devices
10. Power devices: lateral and vertical power devices
11. Advanced device concepts: recent advances in the literature in GaN electronics
