Valence Band Engineering and Polarization Switching in Quantum Dots grown in Inverted Pyramids
2009
2009 Ieee/Leos Winter Topicals Meeting Series (Wtm 2009)
Control on the degree of valence band mixing is experimentally achieved in the particular GaAs/AlGaAs quantum Dot-in-Dot (DiD) structure. The effect is reflected by the tunable polarization of the emitted photons.
