PROJECT OVERVIEW: Quantitative excited state spectroscopy of a single InGaAs quantum dot molecule


  • Study of optical properties in a GaInAs quantum dot molecule
  • Which physical effects govern optical device properties of quantum dots?


  • Extensive atomistic modeling via NEMO3D
  • Consideration of piezoelectric strain effects


  • Good match of experimental excitonic emission spectrum using atomistic modeling approach
  • Strain-induced piezoelectricity to be found crucial in matching optical absorption strengths
  • Published in Nanotechnology, 22, 315709 2011 (M. Usman & Y.-H. M. Tan)
