Abstract
AbstractWe present the polarization dependent photoluminescence from coupled InAs quantum dots. We find polarization memory signatures consistent with those reported for single quantum dots. We also observe a continuous change in the polarization memory of the positively charged exciton as it changes charge configuration due to a hole tunnelling as a function of applied bias. This may provide a method for electrical control of the anisotropic exchange interaction which would be useful for spin manipulation. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
