Cover Story on Nature: Atomic Doping in Nanometer-Scale Crystals
Posted by MSE Supplies on
The Nature magazine featured this materials science research on its cover page of the 27 August, 2015 issue. A group of scientists from the University of Pennsylvania in Philadelphia, PA reported their recent work on the doping of materials at the nanocrystal scale to demonstrate how the physical and chemical properties of nano materials can be engineered at the atomic level by doping. As the authors stated, "Doping is a process in which atomic impurities are intentionally added to a host material to modify its properties. It has had a revolutionary impact in altering or introducing electronic1, 2, magnetic3,4, luminescent5, 6, and catalytic7 properties...
