“…The increase in incorporated amount of hydrogen is related to the low crystalline quality of the film due to increase in non-diamond content [85]. More recently, Shalini et al reported the synthesis of diamond nanowires films using the MPCVD (in Ar-N 2 /CH 4 plasma) [86,87].…”

Diamond is a wide band gap semiconductor exhibiting a combination of superior properties, such as negative electron affinity, chemical inertness, high Young's modulus, the highest hardness and room-temperature thermal conductivity, etc. It is possible to control and enhance the fundamental properties of diamond by fabricating 1D diamond nanowires, due to the giant surface-to-volume ratio enhancements of 1D nanowires. Although theoretical comparisons with carbon nanotubes have shown that diamond nanowires are energetically and mechanically viable structures, reproducibly synthesizing the crystalline diamond nanowires has remained challenging. In this chapter, we present a comprehensive, up-to-date review for the diamond nanowires, wherein we will give a discussing for their synthesis along with their structures, properties and applications.

“…The results showed that the addition of nitrogen to the gas phase increases the non-diamond content in the films. [111] The incorporation of hydrogen in the diamond nanowires was found to increase as the nitrogen in the feed gases in the deposition chamber was increased. Raman spectroscopy measurements show that the increase in the incorporated amount of hydrogen is related to the low crystallinity of the film arising from the increase in the non-diamond content in the samples.…”

“…[114] HCDC-PCVD is an effective method for the deposition of diamond films over a large area and with a high growth rate. Zeng et al reported that (111) diamond microcrystals and (100) diamond microcrystals and nanorods were synthesized on Si substrates by HCDC-PCVD in a CH 4 /H 2 gas mixture. [115] The results showed that a high temperature (1223 K) and low CH 4 concentration led to the growth of (111) microcrystalline diamond films, but a low temperature (1098 K) and high CH 4 concentration can lead to the growth of (100) diamond microcrystals and nanorods.…”

Nanodrähte aus sp3‐C‐C‐gebundenem Diamant sind Halbleiter mit einer breiten Bandlücke und einer Kombination ausgezeichneter Eigenschaften wie einer negativen Elektronenaffinität, chemischer Inertheit, einem hohen Elastizitätsmodul, höchster Härte und höchster thermischer Leitfähigkeit bei Raumtemperatur. Über die Herstellung von 1D‐Diamant‐Nanodrähten können die zentralen Eigenschaften von Diamant durch Erhöhen des Verhältnisses von Oberfläche zu Volumen gesteuert und verbessert werden. Der theoretische Vergleich mit Kohlenstoff‐Nanoröhrchen zeigt, dass Diamant‐Nanodrähte energetisch und mechanisch existenzfähige Strukturen sind – die reproduzierbare Synthese kristalliner Diamant‐Nanodrähte bleibt aber schwierig. Wir geben eine aktuelle und umfassende Übersicht über Diamant‐Nanodrähte, in der wir ihre Synthese, Strukturen, Eigenschaften und Anwendungen diskutieren.
