Ganesh Subbarayan has shared notes from Birck Seminar Series, Thomas Beechem, ME, "Leveraging Light to Enable Tomorrow’s Electronics", Nov 12 . Thomas Beechem, a Purdue Associate Professor, discussed leveraging light for next-generation electronics. He highlighted the challenges of heat transfer in ultra-small devices and the potential of polaritons. Beechem focused on ferroelectrics, particularly hafnia, for memory applications, noting its scalability and non-volatility. He explained the role of oxygen vacancies in device performance, linking them to leakage and imprint issues. Beechem's team uses photoluminescence to probe these vacancies and demonstrated changes in material properties with laser doses. Future work includes combining spectroscopy with near-field imaging to understand defects at the nanoscale and exploring polariton conductance for heat transfer.
