Quantum Engineering of Metallic Nanostructures: From Magic Layers to Quantum Dots
 

Dr. Zhenyu Zhang

Condensed Matter Sciences Div. at Oak Ridge National Lab

Abstract:   Morphological control down to the atomic scale is a critical issue in fabrication of technologically significant nanostructures. In this talk, I will attempt to review some of the latest developments along two lines of active research in nanoscience. The first is the growth of atomically flat metal films on a variety of substrates. Here I will demonstrate, based on both theoretical and experimental investigations, that the application of textbook level quantum mechanics can already lead to the existence of various magic length scales.  The second line of research is on fabrication of quantum dots. Here I will present a few simple ideas that have the promise for mass production of ordered arrays of quantum dots in a wide variety of systems.
