Abstract:

In the last decade, a significant progress has been made towards development of new conceptual paradigms for integrating the nano-structured materials into novel electronic and optoelectronic devices. The systems of nanostructures of interest include, but not limited to, arrays of clusters, nanoparticles, quantum dots and wires, and carbon nanotubes. For a number of potential applications the systems of nanostructures must be ordered and highly homogeneous in size in order to exploit the quantum effects for device applications. In this work, a review of the recent advances in understanding the self-assembly of quantum dots grown on non-planar (patterned) substrates is given. The main emphasis is put on the mechanism of formation of highly ordered arrays of Ge/Si(001) and InAs/GaAs quantum dots taking place during growth on non-planar (patterned) substrates.
