WebDec 21, 2012 · Planar GaAs nanowires were grown on semi-insulating GaAs substrates with three different orientations using a metal–organic chemical vapor epitaxy (MOCVD) reactor. The substrates chosen for this study were on-axis (100), 10° off-cut (100), and (110) substrates. WebWe point out the role of piezoelectricity for InAs/GaAs QDs grown on [11k], where k = 1,2,3,4,5,7,9 and for QDMs containing eight InAs/GaAs QDs grown on [11l], where l = 1,2,3. We predict the variation of the transition energies of the QDM as a function of substrate orientation and interdot distances in the molecule.
