Novel approaches in 2 and 3 dimensional confinement structures: Processing and properties

In this paper we review two novel types of quantum structures. The first, aimed at producing during growth quantum wire superlattices relies on the deposition of tilted superlattices. Some of the difficulties associated with the growth of tilted superlattices and the novel serpentine superlattice have been discussed and solutions proposed. The second type of quantum structures aimed at producing zero dimensional confinement structures relies on the formation of an antidot lattice. The transport properties of antidot lattices with various periodicities are presented.
