Sigalas Michael

His research interests include computational studies of photonic and phononic materials for applications in:

  • optical communications (waveguides, micro-cavity resonators and modulators),
  • lasers and LEDs,
  • sensors,
  • solar cells and
  • thermoelectric materials.

He is also involved in computational studies of:

  • hydrogen storage in nanostructured metal hydrides,
  • absorption spectra of quantum dots and organic molecules for solar cells applications, and
  • phonons and thermal conductivity in nanostructured materials such as graphene and nanotubes.
