We investigate the growth conditions necessary to form an ordered quantum dot crystal by capping spatially ordered quantum dots and growing a new layer of dots on top of the capping layer. Performing Monte Carlo simulations and developing analytic arguments based on the stress energy function, we demonstrate the existence of an optimal capping layer thickness, external flux, and temperature for the formation of quantum dot crystals. © 2001 American Institute of Physics.

    The growth of Pb islands on a Si(111) surface exhibits many interesting properties. For example, the self-assembled process results in a homogeneous distribution of Pb islands with uniform height. The dependence of this height on coverage and temperature can be expressed as a phase diagram [1]....
