Fabrication and electron field emission properties of titanium-oxide nanowire

In this paper, fabrication process of titanium-oxide nanowires, whose diameter and length were in the order of 10 nm and 1 mum, respectively, were successfully fabricated directly on a glass substrate and it´s field-emission properties are discussed, in spite of the poor adhesion. This is profitable in realizing large-diagonal FED´s and BLU´s because glass is less expensive than a Si wafer and a titanium ingot. Scanning-electron-microscope (SEM) observation revealed that there were one-dimensional structures on the surface of the titanium thin film, whose diameter and length were in the order of 10 nm and 1 mum, respectively. Energy dispersive X-ray spectroscopy showed the existence of titanium and oxygen and did not show any silicon signals from the glass substrate, which means successful synthesis of titanium-oxide nanowires in such a simple and low-temperature process.
