Feng Xiong

University of Pittsburgh
Ph.D., Electrical Engineering, University of Illinois at Urbana-Champaign, 2014

Feng Xiong received his Bachelor of Engineering from the National University of Singapore and both his M.S. and Ph.D. in electrical and computer engineering from the University of Illinois at Urbana-Champaign. He was then a postdoctoral fellow in the Department of Electrical Engineering at Stanford University before joining the Department of Electrical and Computer Engineering at the University of Pittsburgh. He received several awards including the Stanford Nano and Quantum Science and Engineering Postdoctoral Fellowship, the Materials Research Society Graduate Student Gold Award, the Beckman Institute Graduate Fellowship, and the Taiwan Semiconductor Manufacturing Company Outstanding Student Research Gold Award.


In today’s big-data era, trillions of sensors will connect every aspect of our lives to the Internet, constantly producing and processing an overwhelming amount of data. Xiong is looking for novel materials for energy-efficient transistor and memory solutions with on-chip thermal management and 3D integration.
Specifically, Xiong is working on:
building wafer-scale energy-efficient 2D transistors, tackling challenges in synthesis, assembly and optimization;
characterizing nanoscale thermal transport in 2D materials, maximizing thermoelectric efficiency through heterogeneous stacking and intercalations for energy harvesting and developing on-chip thermal solutions;
achieving 3D integration of novel low-power memory (resistive and phase change memory) with logic, building energy-efficient flexible memory devices and exploring alternative memory structure with intercalation in layered 2D materials.
