Temperature-dependent field emission (FE) of single crystal TiO 2 nanorods has been investigated. It is found that the FE properties of TiO 2 nanorods are critically affected by environmental temperature of emission tests. As the temperature increases from 290 to 500K, the turn-on field decreases from 2.16 to 1.76V/μm, whereas the current density increases. In addition, the physical...
A facile growth procedure of low-pressure chemical vapor deposition has been developed to synthesize single crystal TiO 2 nanorods on Ni-coated Ti substrate. The results indicate that the as-prepared nanorods are high purity single crystal with a [110] preferential orientation. Using directly the nanorods as emitters, their field emission (FE) properties have been investigated. The turn-on...
