Atomic-scale maps of quantum dots created
University of Michigan physicists say they've created the first atomic-scale maps of quantum dots.
The researchers said their accomplishment is a major step toward the goal of producing
designer dots that can be tailored for specific applications.
Progress in manipulating the atoms in quantum dots to control their properties and behavior has been slowed by the lack of atomic-scale information about the dots' structure and chemical makeup. But researchers say their new atomic-scale maps will help fill that knowledge gap.
The study that included Professor Roy Clarke, doctoral student Divine Kumah, Sergey Shusterman, Yossi Paltiel and Yizhak Yacoby appears in the early online edition of the journal Nature Nanotechnology.
