“…By using this field emission configuration, we can accurately approximate the macroscopic electric field on the surface of the sample ͑i.e., cathode͒ as E = V / d C-A , where V is the voltage applied to the anode and d C-A is the distance between anode and cathode. 11 The voltage is applied using a Stanford Research Systems PS350 power supply, and the emitted current is measured with a Keithley 6517A electrometer. All the measurements were done at a d C-A of 100Ϯ 2 m and at a high vacuum of 1 ϫ 10 −7 Torr ͑1.33 ϫ 10 −5 Pa͒.…”

The temporal stability and electron field emission characteristics of simultaneously grown microcrystalline diamond and carbon nanostructures were investigated. The films were prepared by hot filament chemical vapor deposition using typical diamond deposition parameters, and iron oxide nanoparticles on the molybdenum substrate were employed as catalyst for their induction. The hybrid system presented better emission characteristics compared with microcrystalline diamond with turn-on fields as low as 2.45 V/μm (at 1 μA/cm2), and a current density of up to 0.24 mA/cm2 was achieved. The films showed relatively stable emission behavior for a period of 24 h.

We present a scalable, reproducible and economic process for the fabrication of diamond and diamond-graphene hybrid films using paraffin wax as a seeding source for diamond. The films were characterized using Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electron energy loss spectroscopy (EELS). Raman spectra show the characteristic band of diamond at 1332 cm<sup>-1</sup> and the D, G, and 2D bands of graphene at 1360, 1582 and 2709 cm<sup>-1</sup>, respectively. Electron microscopy confirms the microcrystalline nature of the diamond films with crystal size in the range of 0.5 μm to 1.0 μm, and the hybrid film consists of microcrystalline diamond attached to thin, semi-transparent graphene flakes. The graphene-diamond hybrid films exhibit a turn-on field of about 3.6 V/μm with a prolonged current stability of at least 135 h
