The Nano Defect and Spin Manipulation Group is a dynamical research group created by Prof Han-Chun Wu. At present, we have 2 Postdoctoral Researchers, 8 postgraduate students and 2 undergraduate students. We investigate elementary properties of materials and of nano-devices using both theoretical and experimental methods. Our ultimate goal is to design and prepare new materials for spintronics and information technology. One particular focus of our group at present is to understand how intrinsic and extrinsic defects will affect electronic, magnetic and transport properties of materials and accordingly engineer them to maximize performance. We are also interested in developing new method to manipulate the spin states of magnetic nanostructures.

We are fortunate to have access to a variety of state-of-the-art equipment and cutting-edge facilities through BIT and through international collaboration.
