Welcome to NAMI group!

NAMI group at the University of Southern California focuses on research in nanoscale materials and electronics. The research activities of the group include, but are not limited to, the synthesis and characterization of nanomaterials and structures, and development of novel devices with low power consumption, enhanced operation speed, versatile functionalities and high integration density.

As one of the national initiative, nanotechnology, which exploits materials of dimension smaller than 100 nanometers, is addressing the challenge of the present microelectronic industry and offering exciting new possibilities. This is in accord with Richard Feynman's speech back in 1959, when he described "to synthesize nanoscale building blocks with precisely controlled size and composition, and assemble them into larger structures with unique properties and functions." This vision has continued to spark the imagination of generations of scientists.



Our Research Goals:

Based on the in-depth understanding of various nanomaterials, devices, and systems, and the cutting-edge experimental techniques we employed for years to fabricate and characterize them, our goal is to:

  • To develop novel bottom-up (physical, chemical, and biological assembly) and top-down (lithography) techniques that can create desired nanostructures, devices, and systems with high resolution, reliability, and efficiency.
  • To synthesize high quality nanomaterials (metallic, semiconducting, and magnetic materials) with tailored properties to serve as the building blocks for advanced devices and systems. 
  • To systematically characterize nanomaterials and nanoscale hybrid structures to gain fundamental and comprehensive understanding about their physical properties.  
  • To create nanoscale electronic memory and logic devices with high-density, high-speed, low-power, and multi-functionality.
  • To build advanced nanoscale chemical and biological sensors with enhanced sensitivity, selectivity, reliability, and durability for health and public security applications.
  • To incorporate nanomaterials with polymer materials to develop highly-efficient, low-cost solar cells for energy applications.  
  • To integrate the electronics, sensor, and energy supply building blocks into portable nanoscale systems with signal detection and processing for a wide range of applications.
