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.\n\u003C\/p\u003E\n\u003Cp\u003EWe 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.\n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:david.sherrill@chemistry.gatech.edu\u0022\u003EProf. David Sherrill\u003C\/a\u003E (404-894-4037).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Prof. Barry Dunietz, University of Michigan\n\nExploring Conductance Switching Properties of Molecular Scale  \nDevices - A Computational Approach\n\nPhysical Chemistry Seminar Series","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Barry Dunietz, University of Michigan"}],"uid":"27275","created_gmt":"2008-09-08 00:00:00","changed_gmt":"2016-10-08 01:57:16","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2009-04-28T16:00:00-04:00","event_time_end":"2009-04-28T17:00:00-04:00","event_time_end_last":"2009-04-28T17:00:00-04:00","gmt_time_start":"2009-04-28 20:00:00","gmt_time_end":"2009-04-28 21:00:00","gmt_time_end_last":"2009-04-28 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.umich.edu\/~michchem\/faculty\/dunietz\/index.html","title":"Prof. Barry Dunietz, University of Michigan"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"89","name":"chemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
