INTRODUCTION:

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

METHODOLOGY:

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

RESULTS:

• Good match of experimental excitonic emission spectrum using atomistic modeling approach
• Strain-induced piezoelectricity to be found crucial in matching optical absorption strengths
