"Exploring Conductance Switching Properties of Molecular Scale Devices: A Computational Approach"
Presented by Prof. Barry Dunietz, University of Michigan, Ann Arbor
A computational approach is used and developed to study electron transport through molecular and nano scale devices. New models and methods to describe transient electron conductancethrough molecular systems under the influence of time dependent perturbations are used to studyquantum interference effects affecting the conductance. Coherence-driven processes related to electrontransport are investigated.
We will also describe several studies on molecular scale systems and provide insight into mechanismsunderlying electronic-transport switching properties. Several recent high-profile experimentalstudies achieving molecular scale conductance are considered. These involve metal recognitionproperties of short peptides and fabricated molecular sockets based on surface confined terpyridineligands. If time allows we will also describe: Spin-dependent electronic transport through a Porphyrinring ligating an Fe(II) atom, and contact geometry and orientation effects of conjugatedmolecular field-effect transistors.
