Abstract
We show that forming linear sequences of quantum wells of two different types allows for a rich new variety in energy spectra and density of states for nanostructures. In the case of a one-dimensional periodic array such as a string of dots of two kinds, the phase diagram exhibits a new kind of criticality, in the sense that there are conducting phases arbitrarily close in concentration to any insulating phase, and vice versa.
