Duan Research Group

Hetero-integrated Nanostructures and Nanodevices


  • The Duan Lab’s research interests include nanoscale materials, devices and their applications in future electronics, energy technologies and biomedical science. Our research focuses on rational design and synthesis of highly complex nanostructures with precisely controlled chemical composition, structural morphology and physical dimension; fundamental investigation of new chemical, optical, electronic and magnetic properties; and exploration of new technological opportunities arising in these nanoscale materials. A strong emphasis is placed on the hetero-integration of multi-composition, multi-structure and multi-function at the nanoscale, and by doing so, creating a new generation of integrated nanosystems with unprecedented performance or unique functions to break the boundaries of traditional technologies.

  • Synthesis, Assembly and Characterization. Heterogeneous material integration is central for creating functional systems. Using chemical synthesis and physical assembly approaches, we are developing powerful strategies for the nanoscale integration of highly disparate materials without the limitation of intrinsic material or processing incompatibility.
  • Advanced Electronics and Photonics. Semiconductor electronics and photonics have been the key driving force of the information technology revolution, but are facing substantial challenge for future growth. We are using synthetic chemistry to produce a wide variety of low-dimensional nanostructures, and further assembling them into functional electronic and photonic systems. 
  • Energy Harvesting, Conversion and Storage. As we are facing increasing challenges of diminishing fossil fuel, there is increasing interest in seeking for clean and renewable energy sources. We are developing integrated materials systems for efficient energy harvesting, conversion and storage. 
  • Biomedical Sensing and Therapeutics. With comparable size to functional biological building blocks, nanoscale systems are ideally suited for interfacing with biological systems. We are designing nanoscale electrical and optical systems that can greatly expand our capability in probing, imaging, monitoring, and manipulating biological processes with unprecedented resolution, sensitivity and precision.
