A Gentle Introduction to Nanotechnology and Nanoscience
13 Feb 2006 | Online Presentations | Contributor(s): Mark A. Ratner
While the Greek root nano just means dwarf, the nanoscale has become a giant focus of contemporary science and technology. We will examine the fundamental issues underlying the excitement involved in nanoscale research - what, why and how. Specific topics include assembly, properties, applications, and societal issues.
Molecular Transport Structures: Elastic Scattering, Vibronic Effects and Beyond
13 Feb 2006 | Online Presentations | Contributor(s): Mark A. Ratner, Abraham Nitzan, Misha Galperin
Current experimental efforts are clarifying quite beautifully the nature of charge transport in so-called molecular junctions, in which a single molecule provides the channel for current flow between two electrodes. The theoretical modeling of such structures is challenging, because of the uncertainty of geometry, the nonequilibrium nature of the process, and the variety of available mechanisms. The talk will center on the first formulation of the problem in terms of scattering theory, and then on the generalizations needed to make that simple picture relevant to the real experimental situation. These include vibronic coupling, structural disorder and energy transfer. Some comments will be made on possible switching and rectification schemes.
Energy and Nanoscience A More Perfect Union
29 Mar 2009 | Online Presentations | Contributor(s): Mark A. Ratner
Huge problems of energy and sustainability confront the science/engineering community, mankind, and our planet. The energy problem comes in many dimensions, including supply, demand, conservation, transportation, and storage. This overview will stress the nature of these problems, and offer a few areas where theoretical chemistry can make substantial contributions to solving them. Also discussed are excitons in solar cells and on advanced batteries.
