Light-matter\u0026nbsp;coupling occurs\u0026nbsp;when excitonic transitions\u0026nbsp;of a semiconductor, placed within an optical microcavity, couple with optical modes, i.e., standing electromagnetic waves in the microcavity structure. Weak coupling in these\u0026nbsp;systems can\u0026nbsp;lead to photon quantum phases, while strong coupling leads to emergent hybrid light-matter exciton-polariton states that also\u0026nbsp;display quantum\u0026nbsp;phenomena. Both,\u0026nbsp;photon quantum\u0026nbsp;phases and polariton states represent pathways to modify the properties of light (e.g., spatial and time coherence) and matter (e.g., molecular dynamics and photophysical processes).\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis Ph.D. proposal\u0026nbsp;focuses on\u0026nbsp;how to attain photon quantum phases and exciton-polaritons in organic and hybrid organic\/inorganic semiconductors (e.g., organic dyes and Ruddlesden-Popper metal halide perovskites) to ultimately modify light and matter properties. The first aim of my research is to design and fabricate fully solution-processed microcavities that exhibit the formation of photon quantum phases and strong light-matter coupling in a target semiconductor. The monolithically solution-processed microcavity structures proposed here comprise alternating layers of a high-refractive-index titanium oxide hydrate\/poly(vinyl alcohol) molecular hybrid and a low-refractive-index commodity polymer. These solution-processed microcavities represent\u0026nbsp;a simple alternative\u0026nbsp;to inorganic\u0026nbsp;microcavities and are also expected to be more compatible with temperature-sensitive materials.\u0026nbsp;Second, we will describe the photophysical processes involved in light-matter coupling in organic and hybrid organic\/inorganic\u0026nbsp;semiconductors to\u0026nbsp;deliver a mechanistic understanding of the population and thermalization of photon quantum phases and exciton-polaritons in these material classes. For this purpose, we will employ diverse spectroscopic techniques including k-space microscopy, transient reflectivity and absorption, excitation correlation spectroscopy, and two-dimensional coherent spectroscopy. Last, we will tune photophysical processes\u0026nbsp;involved in\u0026nbsp;light-matter coupling through microcavity design and assess a series of structures for controlling molecular bistable states via light-matter coupling. The overall purpose of this thesis is to reliably attain light-matter coupling in organic and hybrid organic\/inorganic semiconductors and to deliver a detailed understanding of their photophysics for moving toward their utilization in chemistry and quantum information applications.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\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":"\u0022Light-matter coupling in organic and hybrid organic\/inorganic semiconductors\u0022"}],"uid":"27707","created_gmt":"2022-12-16 15:30:30","changed_gmt":"2022-12-16 15:30:30","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-01-17T13:30:00-05:00","event_time_end":"2023-01-17T14:30:00-05:00","event_time_end_last":"2023-01-17T14:30:00-05:00","gmt_time_start":"2023-01-17 18:30:00","gmt_time_end":"2023-01-17 19:30:00","gmt_time_end_last":"2023-01-17 19:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"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":""}}}
