  • Nanoscale lamellar photoconductor hybrids and methods of making same
    Patent number: 8366974
    Abstract: An article of manufacture and methods of making same. In one embodiment, the article of manufacture has a plurality of zinc oxide layers substantially in parallel, wherein each zinc oxide layer has a thickness d1, and a plurality of organic molecule layers substantially in parallel, wherein each organic molecule layer has a thickness d2 and a plurality of molecules with a functional group that is bindable to zinc ions, wherein for every pair of neighboring zinc oxide layers, one of the plurality of organic molecule layers is positioned in between the pair of neighboring zinc oxide layers to allow the functional groups of the plurality of organic molecules to bind to zinc ions in the neighboring zinc oxide layers to form a lamellar hybrid structure with a geometric periodicity d1+d2, and wherein d1 and d2 satisfy the relationship of d1?d2?3d1.
    Type: Grant
    Filed: December 4, 2009
    Date of Patent: February 5, 2013
    Assignee: Northwestern University
    Inventors: Samuel I. Stupp, Josh Goldberger, Marina Sofos
