Abstract
We theoretically studied the elastic deformation and piezo-electric field in InAs quantum dots and InGaAs quantum wires grown on (N11) GaAs substrates. Particular attention was given to the influence of the substrate orientation on both the volume deformation of the dot and the strain-induced piezo-electric field. The influence of the piezo-electric fields on the electron and hole ground states for a (N11) quantum dot and quantum wire was investigated within the envelope function approach. The exciton effect in a quantum wire was studied. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
