Yang Research Group

Our research interest centers broadly on functional nanosystems with an emphasis on semiconductor nanowires. Semiconductor nanowires are single crystal semiconductors with diameters of a few nanometers and lengths up to tens microns. They are versatile building blocks with tunable physical and chemical properties, opening up many exciting opportunities to compute, communicate, encode, detect and identify.

The research programs are currently focused on four major areas: (1) Controlled synthesis of nanowires and nanowire heterostructures; (2) Discovery of novel properties of nanostructures synthesized, with an emphasis on structural, electrical and optical properties; (3) Designing and developing unconventional devices based on nanomaterials for nanoelectronics, nanophotonics and energy applications; (4) Interfacing nanomaterials with biological systems to probe and/or regulate biological activities. Our research programs address scientific issues within these areas using combined ideas and techniques from physical, chemical, biological, and engineering sciences.

We are actively recuiting talented students and postdocs that are motivated to work on nanoscience and nanotechnology. Contact us for details on openings.
