Semiconductors: theoretical studies
Theoretical Research Projects
The general research area is semiconductor physics and semiconductor device
- Hot Electron transport in
FETs: what transport processes affect the performance of a
The Effect of Electron-Electron Scattering on Transport: GaN based devices typically have a very large electron concentrations. How does the rapid interaction between electrons affect devices performance?
- Dynamic Screening and Coupled Mode Effects: static fields are efficiently screened by mobile carriers, but non-static fields such as the polar field produced by an optical phonon fluctuate rapidly. How do the mobile carriers respond?
- Phonons in 2D structures: the spectrum of phonons in layered structures is different from that in bulk material. How does that affect scattering rates and phonon
- Capture into Wells: the rate at which electrons and holes get captured by the wells in a quantum well laser or amplifier contribute to the speed of the device. What determines the rate and how can speed be optimised?
