High throughput approaches to designing electronic ceramics
Shannon Rogers is a first-year Materials Science PhD student in the Advanced Energy Materials group advised by Eric Toberer. Shannon began her studies at Mines in the Fall of 2020 after finishing her B.S. degree in Ceramic Engineering from Alfred University in her home state of New York. She was heavily involved with student organizations at Alfred and continues her passion for outreach here at Mines as Herald of the Mines Keramos chapter, and Co-Student Chair of the American Ceramic Society’s Colorado Section. She has been involved with the ACerS President’s Council of Student Advisors for 3 years now, currently serving as a delegate on the outreach committee. Shannon is interested in energy storage systems and electronic ceramics. She has nearly 3 years of combined industry research experience through internships and cooperative education positions, and hopes to return to industry after completing her PhD to do materials research.
The range of polycrystalline nitride ceramic chemistries in use today is extremely limited. Nitrides such as AlN and Si3N4 are well known and offer unique properties that are lacking in oxide ceramics, which justifies the additional cost and challenge of manufacturing these materials. High throughput computational approaches have dramatically reduced the time required to identify promising new materials of all chemistries, but many complementary high-throughput experimental approaches focus on thin film fabrication techniques that often fail to appropriately represent polycrystalline ceramic materials. This is particularly true for nitrides, leaving massive materials space unexplored. This work aims to develop a high-throughput fabrication capability for powder-derived nitride ceramics to rapidly explore new nitride materials in polycrystalline ceramic form.
