Our group has a long time expertise in optical spectroscopy of semiconductor nanostructures. Recently, we have also built up a new experimental setup to study the acoustically induced modulation of the optical properties of these nanostructures using surface acoustic waves.

We have different  optical setups optimized for the UV, visible, and near infrared  spectral regions which are dedicated to specific needs. In this way, we able to study  carrier and phonon dynamics in our structures in a variety of aspects. Our experimental techniques run at room and low temperatures. They include:

  • Macro photoluminescence (for bulk and thin film samples)
  • Micro-photoluminescence (spatial resolution up to 1 micrometer)
  • Magneto micro-photoluminescence (up to 15 T)
  • Time-resolved micro-photoluminescence (time resolution up to 30 ps)
  • Micro-Raman spectroscopy
  • Photoluminescence of excitation (PLE)
  • Acoustic modulation spectroscopy (CW and time-resolved)
