Promising field electron emission performance of vertically aligned one dimensional (1D) brookite (β) TiO 2 nanorods
We evidence field-electron emission (FE) studies on the large-area array of one-dimensional (1D) brookite (β) TiO 2 nanorods. The pure 1D β-TiO 2 nanorods of 10 nm width and 760 nm long were synthesized on Si substrate utilizing hot-filament metal vapor deposition technique. X-ray diffraction (XRD)...
