• Structure and electronic properties of oxide-oxide interfaces: SrTiO₃ / LaAlO₃

• Structure and growth of transition metal oxides on Si (100): Sr and La adsorption, BaO and SrTiO₃ on Si, etc.

1. electronic excitations, optical properties, and lumiescence, all via ab initio approaches

1. electronic excitations, optical properties, and lumiescence, all via ab initio approaches

1. electronic excitations, optical properties, and lumiescence, all via "ab initio" approaches

Broadly speaking, we are currently interested in problems involving

1. electronic excitations, optical properties, and lumiescence, all via ab initio approaches
2. properties of nanostructures, especially nanowires and nanotubes
3. 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)

For some other information regarding first principles calculation of quasiparticle (transport, band gaps) and optical properties, see the Berkeley CMSN site.

Broadly speaking, we are currently interested in problems involving (1) electronic excitations, optical properties, and lumiescence, all via ab initio approaches; (2) properties of nanostructures, especially nanowires and nanotubes; and (3) the physics of transition metal oxides and their interfaces (as part of CRISP.)
