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.
