Organic molecular layers can provide useful ways to interface oxide materials with organic and biological materials. The Mavrikakis, Hamers, Kuech, Gopalan, and Evans group at the University of Wisconsin MRSEC have collaborated to develop a new way to modify the surface properties of planar ZnO surfaces and of ZnO nanowires. Organic alkenes will graft to ZnO when illuminated with ultraviolet light, producing well defined organic-inorganic interfaces. Computational studies are being used to compare with infrared, Raman, and Photoemission spectroscopies to understand the nature of the bonding and the electronic properties of the interfaces. We anticipate that this will be an attractive method for tailoring the properties of ZnO and other oxides with organic semiconductors.
