The pure 1D beta-TiO2 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) and transmission electron microscopy (TEM) analysis evidenced the beta-TiO2 nanorods to be composed of orthorhombic crystals in brookite (beta) phase. X-ray photoemission spectroscopy (XPS) revealed the formation of pure stoichiometric (i.e. 1 : 1.98) 1D TiO2 nanorods. The values of turn-on field, required to draw current density of 10 mA cm(-2), was observed 3.9 V mu m(-1) for pristine 1D beta-TiO2 nanorods emitters, which were found significantly lower than doped/undoped 1D TiO2 nanostructures (i.e. nanotubes, nanowires, nanorods) based field emitters. The enhanced FE behavior of the TiO2/Si emitter can be attributed to modulation of electronic properties due to the high aspect ratio of vertically aligned TiO2 nanorods. Furthermore, the orthodox emission situation of pristine TiO2/Si emitters exhibit good emission stability and reveal their potentials as promising FE material.1 aDevan, Rupesh, S.1 aMa, Yuan-Ron1 aMore, Mahendra, A.1 aKhare, Ruchita, T.1 aAntad, Vivek, V.1 aPatil, Ranjit, A.1 aThakare, Vishal, P.1 aDhayal, Rajendra, S.1 aSchmidt-Mende, Lukas  uhttps://library.ncl.res.in/content/promising-field-electron-emission-performance-vertically-aligned-one-dimensional-1d-brookite
