The final composition is thereby mainly governed by the initial volume\u0026nbsp;loading of graphene in the plating bath and any applied agitation methods, giving, so far, limited returns in terms of property improvements. Achieving the theoretical maximum material performance requires 1) a high graphene relative content, 2)\u0026nbsp;homogeneous dispersion of graphene throughout the composite, 3) and controlled alignment of graphene within the material. To address this grand challenge, a novel magneto-electrodeposition process is proposed wherein a low-magnitude magnetic field is applied during the plating. Magnetic fields have different, competing effects on electrodeposition depending on their orientation with respect to the plating current direction: Magnetic fields have different, competing effects on\u0026nbsp;electrodeposition depending on their orientation with respect to the plating current direction: 1) graphene aligns along the\u0026nbsp;magnetic field flux lines owing to its diamagnetic properties; 2) the magnetohydrodynamic (MHD) effect allows for\u0026nbsp;increased, localized agitation and, therefore, more uniform distribution of graphene in the copper matrix, and 3) the magnetic field influences ion\u0026nbsp;movement within the electroplating solution, leading to greater graphene content.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis research focuses on assessing the effect of applied magnetic fields on electrodeposited copper-graphene\u0026nbsp;composites in terms of their material composition, microstructure, morphology, and subsequent electrical, mechanical, thermal, and thermomechanical properties for use in next-generation advanced packaging. Key results will demonstrate the effects of magnetic fields on graphene, experimental setup, methodology, and proof-of-concept for magneto-electrodeposition of copper-graphene composites, characterization of morphology and mechanical, electrical, and thermal property improvements, theoretical modeling of potential property improvements of graphene-reinforcement of copper, and finite-element modeling to evaluate the potential benefits of copper-graphene composites in advanced packaging applications.\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":"Magneto-Assisted Electrodeposition of Copper-Graphene Composites: A New Method to Enhance Nanostructure and Properties of Copper in Advanced Packaging"}],"uid":"27707","created_gmt":"2023-01-17 19:57:24","changed_gmt":"2023-01-17 19:57:24","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-01-31T11:00:00-05:00","event_time_end":"2023-01-31T12:00:00-05:00","event_time_end_last":"2023-01-31T12:00:00-05:00","gmt_time_start":"2023-01-31 16:00:00","gmt_time_end":"2023-01-31 17:00:00","gmt_time_end_last":"2023-01-31 17:00:00","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":""}}}
