“…These three deconvoluted peaks are located at BEs of $398.5, $400.0, and $ 401.5 eV, which can be assigned to sp 3 C-N, sp 2 C-N, and N-O bonds, respectively. [21][22][23][24] For the N 1s spectrum of sample B (Fig. 5(e)), only two peaks (one peak is located at $398.5 eV from sp 3 C-N bonds and the other peak is located at $400.0 eV from sp 2 C-N bonds) are needed to fit the spectrum.…”

Competition of nitrogen doping and graphitization effect for field electron emission from nanocrystalline diamond films J.Electron field emission from amorphous carbon nitride synthesized by electron cyclotron resonance plasma Nitrogenated carbon nanotips (NCNTPs) are synthesized by plasma-enhanced hot filament chemical vapor deposition from the hydrogen, methane, and nitrogen gas mixtures with different flow rate ratios of hydrogen to nitrogen. The morphological, structural, compositional, and electron field emission (EFE) properties of the NCNTPs were investigated by field emission scanning electron microscopy, Raman spectroscopy, x ray photoelectron spectroscopy, and EFE high-vacuum system. It is shown that the NCNTPs deposited at an intermediate flow rate ratio of hydrogen to nitrogen feature the best size/shape and pattern uniformity, the highest nanotip density, the highest nitrogen concentration, as well as the best electron field emission performance. Several factors that come into play along with the nitrogen incorporation, such as the combined effect of the plasma sputtering and etching, the transition of sp 3 carbon clusters to sp 2 carbon clusters, the increase of the size of the sp 2 clusters, as well as the reduction of the work function, have been examined to interpret these experimental findings. Our results are highly relevant to the development of the next generation electron field emitters, flat panel displays, atomic force microscope probes, and several other advanced applications.

“…Fig. 3(e) reveals N also has three different bonding energies, i.e., 397.75, 399.83 and 398.39 eV, which can be attributed to spC RN, sp 2 C QN, sp 3 C2N bonding states, respectively [30][31][32]. Conventionally, the N:C molar ratio can be estimated from the areas of the corresponding XPS peaks.…”

“…The direct ion deposition process has been proven to be very effective in the synthesis of thin films with high quality at low temperature because it can control the energy of deposited atoms [8][9][10]. Cesium-assisted sputtering is the one of direct ion deposition techniques leading to negative ionization of deposited atoms.…”
