This project aims at theoretical and experimental study of ZnO nanostructured layers prepared by electrophoretic deposition and study of environmental sensors based on these layers.

(a) Schematic cross section; (b) SEM image of seed layer prepared by EPD of ZnO nanoparticles; (c) Cross-section SEM image of ZnO NRs grown on seed layers prepared by EPD of ZnO nanoparticles.  (d) current-voltage characteristics and (e) current-transient characteristics of the graphite/ZnO NRs junctions.
