Broadly speaking, we are currently interested in problems involving
- electronic excitations, optical properties, and lumiescence, all via ab initio approaches
- properties of nanostructures, especially nanowires and nanotubes
- the physics of transition metal oxides and their interfaces (as part of CRISP.)
Here is a glimpse of topics:
- Electron excitation, optical response, and photoluminescence
- Solid-state defects: e.g. bulk silica
- carbon nanotubes
- molecules
- GaN nanotubes and nanowires
- Other nanostructures
- Physics of boron nanotubes and sheets: structure, electronic states, conductivity, and doping
- Transition metal oxides and their interfaces
- Ab initio Green's function methods for dealing with electron correlations in complex oxides
- Structure and growth of transition metal oxides on Si (100): Sr and La adsorption, BaO and SrTiO3 on Si, etc.
- Structure and electronic properties of oxide-oxide interfaces: SrTiO3 / LaAlO3
For some other information regarding first principles calculation of quasiparticle (transport, band gaps) and optical properties, see the Berkeley CMSN site.
