There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Exploring Conductance Switching Properties of Molecular Scale Devices - A Computational Approach
Physical Chemistry Seminar Series
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 conductance through molecular systems under the influence of time dependent perturbations are used to study quantum interference effects affecting the conductance. Coherence-driven processes related to electron transport are investigated.
We will also describe several studies on molecular scale systems and provide insight into mechanisms underlying electronic-transport switching properties. Several recent high-profile experimental studies achieving molecular scale conductance are considered. These involve metal recognition properties of short peptides and fabricated molecular sockets based on surface confined terpyridine ligands. If time allows we will also describe: Spin-dependent electronic transport through a Porphyrin ring ligating an Fe(II) atom, and contact geometry and orientation effects of conjugated molecular field-effect transistors.
