The Greytak laboratory (Greytak Group) at the University of South Carolina department of chemistry and biochemistry studies the synthesis, physical properties and surface chemistry of nanoscale materials. Prof. Andrew B. Greytak is the principle investigator of the group and there are several gradauate students and undergraduate students work under his research group.The materials group manufacture in the laboratory includes semiconducting nano crystalline quantum dots (QDs) and semiconductor nanowires; the Greytak group also examine a variety of other low-dimension materials in collaborative projects. A great inspiration for this work is the opportunity to impact fields, including energy conversion, energy storage, bioimaging, and biomedicine.[1]
