Theoretical and Computations Chemical Dynamics
My research effort in the past few years has focused on particular types of interfacial systems and processes - those encountered in the evolving field of Molecular Electronics. The possibility that molecules and small molecular assemblies can replace conventional conductors and semiconductors in nano-scale electronic devices has become a subject of intense discussion. The new fundamental issues associated with such systems - the electronic structure, the charge transfer properties, energy transfer and relaxation and the capacitive properties (to name just a few), of molecules connected to conducting leads, present new theoretical and experimental challenges. Recent studies in our group aim at developing theoretical and numerical tools to study electron transmission through such interfaces. A recent series of papers that focus on the electron transmission properties of water, arguably the most important electron transmitting medium, has demonstrated a new resonance effect that explains the observed high efficiency of electron transmission through this medium. More recent work has focused on analyzing the crucial issue of thermal relaxation and heating effects as well as heat conduction in molecular conductors that bear on the question of thermal stability of such systems, and on developing a theoretical framework for understanding inelastic tunneling features and phonon induced non-linear response of molecular conduction junctions. Our current studies aim at analyzing the possibility to probe and control of molecular junctions by light.
