Novel insight into the alignment and structural ordering of supported ZnO nanorods

Supported ZnO nanorods with a different degree of preferential orientation and tunable morphological features were grown on Si(100) by plasma enhanced-chemical vapor deposition. The combined investigation of the synthesized arrays by RHEED and FE-SEM enabled a thorough insight into their structural properties and growth mechanism, whose control is a key issue in view of potential technological applications.
