Interface Engineering for Heat Management, RF Loss, and Optoelectronics in Nanoscale Devices
Presenter: Christine McGinn, UIC
Abstract: As devices move into the nanoscale domain in the post-Moore era, there is a greater need for interface and material engineering to meet the sensing needs of next generation technologies. At low dimensionality, interfacial effects become increasingly dominant, and understanding these interfaces is critical to meeting these needs. Careful choice of substrate and interfacial layers can unlock new advances to existing challenges for semiconductor devices. Ferroelectric materials have been increasingly used to electronically manipulate these interfaces and provide sensing capability in low-dimensional and multifunctional devices, especially the ferroelectric polymer polyvinylidene difluoride trifluoroethylene (PVDF-TrFE), but a comprehensive understanding of its effect on the interface has been lacking. The work presented in this talk studies the role that ceramic and ferroelectric materials can have to solve problems in heat sinking for microLEDs, RF loss at high frequency operation, and optoelectronics.
Speaker bio: Christine McGinn is an assistant professor at the University of Illinois Chicago. She was previously an NRC postdoctoral fellow at the National Institute of Standards and Technology in Gaithersburg, MD. While at NIST, she completed a detail assignment to the CHIPS R&D office assisting the development of a nationwide workforce development strategy for the semiconductor industry. She received a B.S. in Engineering and a B.A. in Physics from Swarthmore College in 2016 and an M.S. and Ph.D. in Electrical Engineering from Columbia University in 2018 and 2022. Her current research studies the interface of two-dimensional transition metal dichalcogenides and ferroelectric materials for photodetection applications and past research focused on sensing applications of piezoelectric and ferroelectric materials.
