Surface tension and fluid flow driven self-assembly of ordered ZnO nanorod films for high-performance field effect transistors

The self-assembly process and the correlation with device performance are studied through ZnO nanorods. It is seen that uniform ZnO nanorod films with defined nanorod alignment can be solution-deposited over large areas by controlling the surface energy of the nanorods through the choice of suitable ligands and by the fluid flow direction during growth.
