A Sonochemical Method for Fabricating Aligned ZnO Nanorods

Fabrication of arrays of vertically aligned ZnO nanorods by a simple sonochemical route is demonstrated (see figure). The nanorods can be grown in situ over large areas at a high density under ambient conditions—important for nanoelectronic circuit integration—and on various substrates, including transparent glass and polycarbonate. Growth of the nanorods in patterns using a lithographic technique is also described.
