“…The increase of defects concentration is confirmed by the Raman spectra of figure 3 showing broadening of the diamond Raman line. The conversion of a N S 0 to the N S + state is responsible for disappearing of hyperfine ESR structure but the other processes should be considered: either aggregation of single nitrogen atoms or direct N 2 incorporation in each case by capture of a vacancy [27].…”

Defects in nitrogen-doped diamond films, produced by hot filament chemical vapour deposition have been studied by Electron Spin Resonance (ESR), Raman spectroscopy and Scanning Electron Microscopy (SEM). The peak-to-peak ESR line width (∆H pp ) varies in the range 0.36-0.52 mT and depends on the nitrogen concentration in the process gas. In the case of nitrogen-doped diamond films ESR spectrum shows a hyperfine structure typical of N S 0 paramagnetic centre. The shape of the central ESR line shows that it is a superposition of two components: a narrower Lorentzian and a broader Gaussian one, characterized by different saturation behaviour. With increasing nitrogen concentration in process gas the ratio of integral intensities A G /A L (Gausian to Lorentzian) of ESR spectrum also increases. The Raman spectra show that with increasing doping level the diamond Raman line at 1332.5 cm -1 broadens, the broad band at about 1530 cmbecomes more pronounced what indicate on degradation of diamond crystallinity and it is in agreement with SEM observation.

“…Indeed, luminescence spectra typically show the 5RL, 3.188, and 2.807 eV systems in asgrown CVD diamond (Partlow et al 1990, Sternschulte et al 1996, Lin et al 1996. The 3H centre has also been detected by means of PL in as-grown CVD films (Iakoubovskii and Adriaenssens 2000a).…”

“…There is a common belief that due to the low deposition temperature there should be no nitrogen complexes in CVD diamond. However, some CVD films show PL lines from the [2N S -V] 0 (H3) centres (Collins et al 1990, Lin et al 1996. This PL can be particularly strong in 100 -oriented CVD films and HPHT crystals.…”

This work discusses the current situation in the study of bulk defects in diamond, grown by chemical vapour deposition (CVD), using optical absorption, luminescence, and electron spin resonance techniques. CVD diamond appears distinct from other types of diamond in that it exhibits significant concentrations of bulk defects involving hydrogen, silicon, and possibly tungsten impurities. Importantly, as regards doping, p-type conductivity up to the degeneracy level can be achieved by boron incorporation, while n-type conductivity can be realized by phosphorus doping. A generally observed trend is cross fertilization between the studies of various types of diamond: the knowledge of the properties of intrinsic and irradiation-induced defects, obtained from extensive studies of natural and high-pressure synthetic diamond crystals, helps in understanding the presence of certain radiation-damage-related centres in as-grown CVD films. In return, some achievements from the study of defect centres in CVD diamond may provide useful information for modelling of defects in crystalline diamond and other semiconducting materials.

“…The preferential etching on graphite than diamond by active hydrogen atoms in the plasma makes the growth of CVD diamond films become true [30]. In addition to the slight nitrogen defects in CVD diamond from the latent background or feeding gas, the morphology and growth strategy of CVD diamond can be regulated by the nourishing of nitrogen [31]. As shown in Figure 2(a), during the HPHT synthesis, the crystallization process exhibits several stages with the rising of nitrogen concentration, ie from single crystal to block crystal with micro-twins and then to aggregate of crystals and/or twins.…”

the burgeoning multi-field applications of diamond concurrently bring up a foremost consideration associated with nitrogen. Ubiquitous nitrogen in both natural and artificial diamond in most cases as disruptive impurity is undesirable for diamond material properties, eg deterioration in electrical performance. however, the feat of this most common elementnitrogen, can change diamond growth evolution, endow diamond fancy colors and even give quantum technology a solid boost. this perspective reviews the understanding and progress of nitrogen in diamond including natural occurring gemstones and their synthetic counterparts formed by high temperature high pressure (hPht) and chemical vapor deposition (cVD) methods. the review paper covers a variety of topics ranging from the basis of physical state of nitrogen and its related defects as well as the resulting effects in diamond (including nitrogen termination on diamond surface), to precise control of nitrogen incorporation associated with selective post-treatments and finally to the practical utilization. among the multitudinous potential nitrogen related centers, the nitrogen-vacancy (NV) defects in diamond have attracted particular interest and are still ceaselessly drawing extensive attentions for quantum frontiers advance.
