Title:
Design and realization of low density InAs quantum dots on AlGaInAs lattice matched to InP(001) 
Abstract:
We present detailed growth studies of InAs nanostructures grown on AlxGayIn(1−x−y)As lattice matched to an InP(0 0 1) substrate using molecular beam epitaxy. Highly elongated quantum dash like structures are typically favoured in this material system, due to very anisotropic migration lengths along the [1 −1 0] and [1 1 0] directions. In order to increase the short migration length along the [1 1 0]-direction we used ultra low growth rates down to 3×10−3 monolayers per second. We show that this...    »
