Abstract

The aligned SnO2 nanotube arrays on Si substrate have been prepared via liquid-phase deposition with the solution system of SnF2 utilizing ZnO nanorod arrays as sacrificial template. The SnO2 nanotubes are distributed uniformly and grown perpendicularly to the substrate. The SnO2 nanotubes are rutile phase with the outside diameter of ~190-310 nm and the wall thickness of ~45 nm. The template-related growth mechanism for the formation of SnO2 nanotube is investigated. Experimentally, the SnO2 nanotube array shows an efficient field-emission property, which is favorable for realizing high performance cold cathode electron emitters.
