In a project funded by NSFC,Professor Li Guodong and colleagues at the National Center for Nanoscience and Technology in Beijing made a new breakthrough in understanding the way electrons travel around quantum dots.This might lead to promising new fabrication methods of novel quantum devices,as they reported in Journal of Applied Physics,published by the American Institute of Physics in October 2010. According to their report,Professor Li and his research team carried out an experiment using self-assembled quantum dots and a two-dimensional electron gas,and then fit the data to a model to find out the In a project funded by NSFC, Professor Li Guodong and colleagues at the National Center for Nanoscience and Technology in Beijing made a new breakthrough in understanding the way dynamics travel quantum dots.
