Growth and characterizations of organized nanostructures

The research investigations and progresses in nanotechnology and the efforts to fabricate novel nanostructures are expected to provide new perspectives into the understanding of underlying science and the formation mechanisms of nanostructures and thus providing the potential for the next-generation device applications. The potential impact of the nano-devices to our society could be extremely enormous and thus the fabrication, engineering and designing of new configuration of nanostructures have attracted a tremendous attention from a number of research fields.;In Chapter 1, a brief introduction to the growth & characterization of organized nanostructures is given. Chapter 2 discusses about the growth and fabrication effort of localized quantum structures by using Stranski-Krastanov (SK) growth model on shallow patterns (35nm), namely quantum dots, quantum dot chain, quantum wires and the related research. Chapter 3 introduces the growth and characterization of novel nanostructures using Volmer-Weber (V-W) growth model. More specifically, the formation of metal droplets, the fabrication of ring-shaped nanostructures and various configurations of nanostructures using droplet epitaxy are presented. Chapter 4 explains the formation mechanisms and the optical properties of quantum dot molecules (QDMs), a hybrid nanostructure composed of a pair of a metal particle, a semiconductor quantum ring (QR), and various advanced nanostructures. Chapter 5 concludes the dissertation with some concluding remarks.
