Chapter 2 reviews select semiconductors and optoelectronics with an emphasis on the infrared (IR) and visible spectra absorption. Chapter 3 presents the preliminary research used to extract fundamental material properties. The proposed research is detailed in Chapter 4, further investigating the trap states in TiO2-x Schottky diodes, the indirect-to-direct band transition in Ge1-xSnx with increasing Sn concentration, and the performance degradation of on-orbit Si, CZTS, and perovskite solar cells due to radiation displacement damage.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Carrier Transport and Defect Dynamics in Advanced Optoelectronics: Deep-level Characterization, Lifetime Engineering, and Radiation Effects"}],"uid":"28475","created_gmt":"2025-11-22 09:22:59","changed_gmt":"2025-11-22 09:24:08","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-12-03T10:00:00-05:00","event_time_end":"2025-12-03T12:00:00-05:00","event_time_end_last":"2025-12-03T12:00:00-05:00","gmt_time_start":"2025-12-03 15:00:00","gmt_time_end":"2025-12-03 17:00:00","gmt_time_end_last":"2025-12-03 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Room W218, Van Leer","extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"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":""}}}
