Abstract:
Physicists in the US have moved a step closer to controlling the electronic properties of individual molecules in a condensed matter environment. Michael Crommie and colleagues at the University of California at Berkeley and the Lawrence Berkeley National Laboratory have demonstrated a new way to "dope" single carbon-60 molecules with potassium atoms. The team says its method is the molecular equivalent of the n-type doping that is widely used in the semiconductor industry. (more on earlier article)
