Electrochemical reactivity and ionic transport in these systems is, however, a complex process, controlled by the interplay of charge injection and field-controlled and diffusion-controlled transport, which are often very sensitive to the environmental conditions, microstructures and defect structures of the material.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis research uncovers complex ionic dynamics in functional oxides via energy discovery platforms, which combine microfabricated lateral devices with in-situ characterization techniques. To be specific, the water decomposition reactivity and proton conduction mechanisms are investigated in two ionic conducting oxides: nanostructured ceria (NC) and yttrium-doped barium zirconate (Y-BZO). By utilizing characterization techniques such as time-resolved Kelvin probe force microscopy (tr-KPFM), electrochemical impedance spectroscopy (EIS) and theoretical analysis such as finite element method (FEM), the effects of external conditions such as temperature, humidity and atmosphere and internal conditions such as film crystallinity, surface roughness, dopant concentration and lattice strain on the transport mechanisms of these materials systems are identified.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe comprehensive structure-property relationship study of these materials not only showcases the feasibility of energy discovery platforms in complex ionic dynamics study on the nanoscale, but also facilitate material and device design with better performance and reliability.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"PROBING COMPLEX IONIC DYNAMICS ON THE NANOSCALE VIA ENERGY DISCOVERY PLATFORMS"}],"uid":"27707","created_gmt":"2017-04-28 18:18:14","changed_gmt":"2017-04-28 18:18:14","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-05-12T10:00:00-04:00","event_time_end":"2017-05-12T12:01:00-04:00","event_time_end_last":"2017-05-12T12:01:00-04:00","gmt_time_start":"2017-05-12 14:00:00","gmt_time_end":"2017-05-12 16:01:00","gmt_time_end_last":"2017-05-12 16:01:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
