Description

The uniform and highly dense nanopillars of rutile TiO2 were synthesized by the hydrothermal method and demonstrated as a highly intense source for the application in field electron emission. The TiO2 nanopillars formed by a bunch of the many nanorods were nearly perpendicular to FTO substrate. The stoichiometric composition and chemical properties of Ti and O were confirmed by X-ray photoelectron spectroscopy. The rutile TiO2 nanopillars transferred on the carbon tape to prepare cathode for field emission (FE) performance exhibit the superior current density of 1.03 mA/cm2 at the applied electric field of 3.2 V/µm, and the lower turn-on field of 1.2 V/µm defined at a current density of 10 µA/cm2. The result of the FE revealed that rutile TiO2 nanostructure enhances the FE without any coating, doping, and surface modifications.
