This thesis proposes to investigate how targeted chemical modifications at the organic\u2013inorganic interface govern the ground\u2011state structural stability and excited\u2011state lattice response across perovskite dimensionalities. In Objective 1, molecular modulations of phosphonic acids will be used to probe how hydrogen\u2011bonding interactions stabilize the \u03b1\u2011FAPbI3 phase and suppress formation of the non\u2011perovskite phases. Objectives 2 and 3 will extend this framework to low\u2011dimensional perovskites, where the structure and dynamic motion of spacer cations dictate octahedral distortions, lattice flexibility, and exciton\u2013phonon coupling. Objective 2 will establish how monodentate versus bidentate binding modalities and the chemical nature of the anchoring groups modulate the rigidity of the inorganic lattice and its susceptibility to photoinduced deformation, thereby tuning exciton dressing and the scattering pathways that govern dephasing. Building on these insights, Objective 3 will examine how lattice flexibility influences the emergence of superfluorescence by comparing phenethylammonium, chlorinated\u2011phenethylammonium, and benzene\u2011based bidentate cations, determining whether molecular control over lattice dynamics can modulate coherence decay and the conditions required for cooperative emission. Together, these proposed studies aim to reveal how organic\u2013inorganic interactions regulate structural stability and photoinduced lattice dynamics, establishing molecular\u2011level design principles for advancing the optoelectronic and quantum photonic capabilities of lead halide perovskites.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EStructure\u2013Property Relationships in Lead Halide Perovskites: From Phase Stability to Collective Optical Phenomena\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Structure\u2013Property Relationships in Lead Halide Perovskites: From Phase Stability to Collective Optical Phenomena"}],"uid":"27707","created_gmt":"2026-08-19 14:54:16","changed_gmt":"2026-08-19 14:54:49","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-08-28T10:00:00-04:00","event_time_end":"2026-08-28T12:00:00-04:00","event_time_end_last":"2026-08-28T12:00:00-04:00","gmt_time_start":"2026-08-28 14:00:00","gmt_time_end":"2026-08-28 16:00:00","gmt_time_end_last":"2026-08-28 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"MRDC Room 4211 and\/or   Virtually via MS Teams ","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":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
