“…BDD is one of the most developed and well known "diamond-based" electrode materials. 40,[83][84][85][86][87] It is also well known that BDD electrodes exhibit excellent levels of performance. For example, a BDD surface exhibits superior anti-fouling properties against biomolecules.…”

“…This unavoidable graphitic component also plays a prominent role in the case of pointed emitters, and the control of the sp 2 inclusions is nowadays a fundamental issue pursued in several laboratories. It is to be noted that the shaping of diamond in 1D nanostructures is also gaining quite an important place for other applications, such as DNA sensing, 128 bio-and electro-chemistry, 87 gas sensing 129 and quantum information. 130 The final considerations regard the practical implementations of FE-based innovative devices that take advantage of the outstanding properties of nanodiamond.…”

The aim of this review is to highlight the recent advances and the main remaining challenges related to the issue of electron field emission (FE) from nanodiamonds. The roadmap for FE vacuum microelectronic devices envisages that nanodiamonds could become very important in a short time. The intrinsic properties of the nanodiamond materials indeed meet many of the requirements of cutting-edge technologies and further benefits can be obtained by tailored improvements of processing methodologies. The current strategies used to modulate the morphological and structural features of diamond to produce highly performing emitting systems are reported and discussed. The focus is on the current understanding of the FE process from nanodiamond-based materials and on the major concepts used to improve their performance. A short survey of non-conventional microsized cold cathodes based on nanodiamonds is also reported. IntroductionMiniaturized electron sources based on the field emission (FE) process, namely "cold-cathodes", are nowadays replacing the conventional thermoionic electron sources. FE-based devices are able to operate at high frequency and at high current densities, have no need of heating and are characterized by reduced weight and by instantaneous switching on. Moreover, Maria Letizia TerranovaProfessor of Chemistry at Tor Vergata University of Rome (Italy), Maria Letizia Terranova heads the Minima lab at the Department of Chemical Science and Technology. She has expertise on different scientific topics, including nuclear chemistry, laser-induced reactions in the gas-phase, ion-and laserinduced modifications in solids, electrochemical and vapour deposition processes. Her research activity is mainly focused on the synthesis, processing and functional testing of nanomaterials: carbon nanostructures (nanodiamonds, nanotubes, graphenes, onions), nanocomposites and hybrid organic/ inorganic structures. Materials and systems are produced for applications in micro/nano-electronics, optoelectronics, energetics, sensing, thermal management and bio-related nanotechnologies. She has co-authored 290 papers, 4 patents, and co-edited 4 books. Silvia OrlanducciIn 2004 Fowler-Nordheim and the experiments by Spindt and coworkers 3 paved the way for a number of subsequent researches on FE-based vacuum electronics. The good performance of such devices is based on the fact that, according to the Fowler-Nordheim law, the emitted current density J depends strongly on the local applied electric field E and that geometric factors typical of nanostructures (sharp edges, tips, peaks, nanoprotrusions) locally increase the concentration of electric field at the emitter sites. The ratio of the local field to the applied field, the so-called electric field enhancement factor β, 1 independently of the material, is a key factor influencing the field emission characteristics. In the last two decades the design, realization and application of a new generation of cold cathodes based on advanced nanomaterials have been the object of tremendous i...

“…23,24 The etching process was stopped (by trial and error) once the masking ND particles were also etched away by the O 2 plasma so as to prevent the plasma damage on the formed nanorods. Such a technique is similar to Yang's process, 25 which utilized ND particles as a mask in a RIE process for fabricating the diamond nanorods from ultrananocrystalline diamond films.…”

Vertically aligned diamond-graphite hybrid nanorod arrays with superior field electron emission properties

et al. 2017

A “patterned-seeding technique” in combination with a “nanodiamond masked reactive ion etching process” is demonstrated for fabricating vertically aligned diamond-graphite hybrid (DGH) nanorod arrays. The DGH nanorod arrays possess superior field electron emission (FEE) behavior with a low turn-on field, long lifetime stability, and large field enhancement factor. Such an enhanced FEE is attributed to the nanocomposite nature of the DGH nanorods, which contain sp2-graphitic phases in the boundaries of nano-sized diamond grains. The simplicity in the nanorod fabrication process renders the DGH nanorods of greater potential for the applications as cathodes in field emission displays and microplasma display devices.
