Summary of degenerate pump-probe experiment on SiGe QWs for nonradiative lifetime estimation
 FELBE beamtime 04-07 April 2019

  • : alignment and measure of a rectangular structure (2261) featuring intersubband transition above the longitudinal - optical phonon. FEL wavelength 26.5 mm.
  • : measure of a rectangular structure (2263) featuring intersubband transition below the longitudinal - optical phonon and of an asymmetric-coupled QWs structure (2217). FEL wavelength 45.8 mm.
  • : measure of the same rectangular structure (2263) and of a step well (2264). FEL wavelength 52.6 mm.
  • : measure of the same rectangular structure (2263), of the step well (2264) and of another ACQW (2216) at much lower pump intensities. FEL wavelength 45.8 mm and 52.6 mm.
