“Nanowire and Nanomembrane Electronics: Performance and Scalability”

Abstract: This talk will focus on several platform nanotechnologies developed at Illinois. First, I will introduce a method to realize scalable 3D III-V transistors using MOCVD grown planar nanowire arrays. Planar nanowires represent a new nanowire paradigm that is self-aligned, defect-free, transfer-printable, and compatible with planar processing technologies. Monolithically grown HEMTs using GaAs planar nanowire array as the channel will be shown with record fT/fmax. I will then discuss strain-induced self-rolled-up membrane (S-RUM) technology and its applications in dramatic (10 – 100X) miniaturization and performance enhancement of passive electronic devices (including inductors and transformers); and guiding and accelerating neuron cell growth. Finally, vertical nanowire based solar cells and LEDs grown on heterogeneous substrates via direct or selective area epitaxy or fabricated using the anisotropic metal-assisted chemical etching (MacEtch) method will be discussed.
Bio: Xiuling Li received her Ph.D. degree from the University of California at Los Angeles. Following post-doctoral positions at California Institute of Technology and University of Illinois, as well as industry experience at a startup company EpiWorks, Inc., she joined the faculty of the University of Illinois in 2007 as an Assistant Professor in the Department of Electrical and Computer Engineering. She was promoted to Associate Professor with tenure in 2012, and to Professor in 2015. Her research interests are in the area of nanostructured semiconductor materials and devices. She has won the NSF CAREER award (2008), DARPA Young Faculty Award (2009), ONR Young Investigator Award (2011), the Dean’s Award for Excellence in Research (2012), Andrew T. Yang Research Award (2013), Willet Faculty Scholar Award (2015), and Faculty Entrepreneurial Fellow (2015). She has >110 publications in referred journals and >16 patents, including the metal-assisted chemical etching (MacEtch) technology, planar nanowire growth method, and self-rolled-up membrane (S-RUM) based miniaturized passive electronic devices and components. She is a Distinguished Lecturer of the IEEE Nanotechnology Council, a Deputy Editor of Applied Physics Letters, and serves on the Board of Governors of the IEEE Photonics Society, and the program committees of several international conferences.
