Abstract :

This talk presents some interesting topics addressing the surface effect on physical properties and potential applications of nanostructured ZnO. The surface effects including surface band bending, chemisorption/ photodesorption/biosorption near surfaces, and native surface defects/states are more pronounced in the nanostructures than that in thin film and bulk counterparts due to the structural uniqueness and the ultrahigh surface-to-volume ratio of ZnO nanostructures. The surface effect constituting the basis for developing novel applications of ZnO nanostructures trigger an increase of interest from understanding on how the physical properties are affected by shrinking dimension or size of ZnO to putting the 1D ZnO nanodevices for ultrasensitive chemical/photo/bio detection in practice.
