A team of physicists from the Paul-Drude-Institut für
Festkörperelektronik (PDI) in Berlin, Germany, NTT Basic Research Laboratories
(NTT-BRL) in Atsugi, Japan, and the U.S. Naval Research Laboratory (NRL) has
used a scanning tunneling microscope to create quantum dots with identical,
deterministic sizes. The perfect reproducibility of these dots opens the door to
quantum dot architectures completely free of uncontrolled variations, an
important goal for technologies from nanophotonics to quantum information
processing as well as for fundamental studies. The complete findings are
published in the July 2014 issue of the journal Nature Nanotechnology.
