“…1350 cm −1 is a combination of the diamond ZCP and the B2 bands antiresonances. The Fano asymmetric parameter values of the B2 band are remarkably close to the ones of the ZCP line, which are consistent with values reported in the literature [1][2][3][4][5][6] and the position and the width of the diamond line are also consistent with our previous report [20]. The fitting peak position of the B2 band (1250 cm −1 ) corresponds to the reported maxima of diamond PDoS [16] which supports our analysis and confirms the PDoS origin of this band.…”

“…This analysis indicates that the difference between the apparent position of the B1 band and the position of the maximum of PDoS in disordered diamond is not only due to phonon confinement but it is also due its interaction with electronic Raman scattering, i.e. Fano effect, conformably with the ZCP line [20]. This analysis is also analogous to Yogi et al work on silicon nanostructures who report the observation of a size-dependent position asymmetric peak due to acoustic phonons by Raman spectroscopy due to the quantum confinement effect and their interaction with intraband quasi-continuum [33].…”

“…[22], whereas sample S2 was grown with a higher boron to carbon ratio of 40,000 ppm on a (111) oriented substrate using deposition conditions reported in ref. [20]. Raman spectra were measured using a LabrRAM HR spectrometer from Horiba Jobin-Yvon interfaced to an Olympus microscope with a 100× objective and a 50 μm confocal aperture, and a HeNe laser 633 nm (1.96 eV) with 8 mW power.…”

“…The broad asymmetric band B1 is empirically modeled with the sum of a Lorentzian and a Gaussian [18] or a Lorentzian component [1]. It is very sensitive to the boron concentration [19,20] and it was attributed to vibration modes of boron dimers [18,21]. However, substitutional isotopic studies have failed to unambiguously confirm this assignment [12,14].…”

Lattice disorder, electronic Raman scattering, and Fano interaction effects are at the genesis of the Raman spectrum of heavily boron-doped diamond. However, no accurate unified description of this spectrum has been reported yet. In this work, we propose a novel analysis of the Raman spectrum of boron-doped diamond based on classical models of electronic Raman scattering and Fano effect. This new analysis shows that the Raman spectrum of boron-doped diamond results from the combination of electronic Raman scattering and its interaction, i.e. Fano effect, with the diamond phonon density of states and it confirms the 500 cm −1 and 1200 cm −1 bands originate from the phonon density of states.

“…825 o C, as measured with a disappearing filament optical pyrometer. These deposition conditions produced a diamond film that was ∼2–4 μm thick with a doping level in the low 10 21 cm ‐3 range, based on Raman spectroscopic analysis , and an electrical resistivity of ≤0.01 ohm‐cm. At the end of the deposition, the CH 4 and B 2 H 6 flows were stopped.…”

Isatin is an endogenous indole compound in humans and rodents that has a wide range of biological activity. In rat models, isatin concentrations have been shown to increase in the heart, brain, blood plasma, and urine with stress. Studies on patients suffering from Parkinson's disease have indicated a correlation between progress of the disease and urinary output of the molecule. Isatin is electrochemically active and can therefore be detected with electrochemical techniques. In this work, we compared the performance of a nitrogen‐incorporated tetrahedral amorphous carbon (ta‐C:N) and a boron‐doped nanocrystalline diamond thin‐film electrode for the oxidative detection of this biomolecule using flow injection analysis with amperometric detection. The measurements were performed in 0.1 phosphate buffer pH 7.2. The ta‐C:N electrode, like boron‐doped nanocrystalline diamond, exhibits some excellent properties for electroanalytical measurements including (i) low background current and noise, (ii) microstructural stability at positive detection potentials, and (iii) good activity for a wide range of bioanalytes without conventional surface pretreatment. The results reveal that both electrodes exhibit a linear dynamic range from 100 to 0.1 μmol L−1, a short‐term response variability 3–4 % RSD (30 injections), a sensitivity of 18 mA M‐1, and a limit of detection (S/N=3) of 1.0×10−7 mol L−1 (14 ng mL−1 or 2.5 fmol).

graphite, etc., diamond has attracted significant research attention, due to its exceptional mechanical, chemical, and physical properties granted by sp 3hybridized carbon bonding. [1] Advances in the synthesis of diamond in the form of polycrystalline coatings have driven a rapid development of numerous applications-to date, applications span from quantum-based, biological/biomedical, wastewater treatment, ozone generation to micro/nano-electromechanical systems, and many others. [2] Many of the aforementioned applications are reliant on the ability of diamond to conduct electrical current, which is attained in a controllable manner by the introduction of boron atoms into the diamond lattice during synthesis of boron-doped diamond (BDD). [3] In the field of electrochemical engineering, polycrystalline BDD in the form of electrodes are widely recognized for their sustained microstructural stability amid harsh anodic and cathodic polarizations, along with insusceptibility to molecular adsorption and fouling, which contributes to the growing use of BDD electrodes in multiple electrochemical research studies and applications. [4] Although, at present several polycrystalline diamond products are commercially available, a number of applications that rely on properties granted exclusively by diamond are expected to benefit from significant enlargement of the diamond surface area available per unit volume. [5,6] In particular, industrial electrochemical processes (e.g., oxidation of organic contaminants in wastewater via BDD electrodes), which generally require utilization of expensive and large electrochemical reactors, would profit from an enhanced product-generation rate per unit volume that scales with the surface of the electrode, therefore enabling economic benefits due to a significant reduction of the volume of the reactor.A number of works have recently reported on the enlargement/structuring of polycrystalline BDD coating surfaces, which is achieved via three distinctive fabrication approaches: i) etching of diamond with various surface masks (i.e., top-down Highly functional 3D biological systems, which are ordinary in this physical world, suggest that traditional planar/flat materials when assembled into 3D variants, can deliver significantly higher levels of functionality and efficiency. Thanks to its set of unique properties, diamond has received significant recognition as the material of choice for a variety of functional platforms, however, implementation of diamond in real-world applications has lagged behind alternative materials, which offer a greater degree of versatility. In this regard, for applications to benefit from diamond-specific properties, approaches on fabrication of diamond beyond the common planar form in a practical and scalable manner are required today. Capitalizing on the ability to synthesize diamond over large areas, this study demonstrates fabrication of porous borondoped diamond (BDD) in freestanding form and on wafer-compatible sizes. Porous BDD electrodes deliver robust ele...
