Hetero-integrated Nanostructures and Nanodevices

Research

  • 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 of 2D crystals/heterostructures. Synthesis of 2D materials with precisely controlled composition, dimension and heterostructure interface is central for exporing science and technology at the limit of single atomic thickness.
  • High speed flexible electronics. 2D atomic layers (e.g., graphene, MoS2) can enable a new generation of atomically thin electronics with unprecedented speed and flexiblity.
  • van der Waals heterostructure device. van der Waals interation between 2D layers can allow flexible integration of distinct materials to enable novel electronic and optoelectronic devices not otherwise possilble.
  • 3D graphene for energy storage. 3D graphene framework can function as a high surface area electrode for creating diverse energy storage devices with unprecedented combination of energy and power density.
  • Nanoscale catalysis. Nanoscale integration of highly disparate materials and molecules of distinct electronic structure or chemical function, can open exciting possibllity to tailor the chemical reactivity and enable novel catalysts for the reduction of O2, CO2 or N2. 
  • Nanoprobes for chemistry and biology. With the critical dimension matching well with the fundamental functional units in chemistry and biology, nanoscale structures and devices can fofer powerful ways to probe molecular pathway in chemistry and biology.
