“…These absorption spectra of the DLC film have been de-convoluted into three peaks; they are due to anti-symmetrical vibrations of sp 3 -CH3, vibrations of sp 3 -CH, and symmetrical vibrations of sp 3 -CH2 [21].The spectra are dominated by two peaks at ~2850 cm -1 and 2920 cm −1 , which could be related to the sp 2 -CH group and sp 3 -CH modes, respectively. Two highly dense peaks at 1732cm -1 and 1717cm -1 determine the C=O at 2% and 10% concentration of acid in solution respectively.…”

Diamond-like carbon (DLC) is widely studied for various applications such as optoelectronics, energy, aerospace, and medicine. It’s hard, chemically inert, and optically transparent. Due to its superior antireflection properties, DLC films are more suited for photovoltaic technology. Here in this work, we report a facile, high speed, and low-cost method of DLC film development from an aqueous solution via electrodeposition. The effect of applied voltage and solution concentration on the properties of DLC film was analyzed. The morphology, shape, and uniformity of the DLCs were analyzed with optical and electron microscopies. The presence of C-H, C-C, and C=C bonds in the DLC films was confirmed from FTIR and Raman spectroscopies. Whereas the optical behavior was analyzed with a UV-Vis-NIR spectrophotometer. The DLC films were deposited at 2.7 V, 4V, 6V, 8V, and 10V, and it was shown that for a fixed electrolyte concentration and electrode spacing, the applied voltage can be adjusted to obtain varying deposition rates. Likewise, the solution concentration was varied in the 2 vol.% to 10 vol.%, and it was demonstrated that by increasing the solution concentration the deposition rate increases. The increase in the deposition rate was evidenced by an increase in the deposition current as well as the roughness of the films. It was noticed that smaller-sized, well-defined, and more uniform DLC films were obtained at lower concentrations and low voltage levels. The band gap was varied between 2.91ev to 3.39ev. It was clearly shown that reflection reduced remarkably after depositing DLC film on the substrate surface. This work demonstrates that DLC film has a potential to utilized as an antireflection layer in photovoltaic application.

“…Тонкие DLC-пленки, с одной стороны, уже применяются в промышленности в качестве различного рода оптиче-ских и защитных покрытий [3], а с другой -продолжают оставаться объектом активного исследования. Так в работе [4] продемонстрировано увеличение эффективности кремниевых солнечных элементов после напыления просветляющей DLC-пленки. Показаны перспективы их ис-пользования и для высокочувствительных тонкопленочных резистивных термометров, работающих вблизи комнатной температуры [5], для создания оптически прозрачных инертных электродов в приложениях электрохимии [6,7], для создания датчиков давления на основе диодов Шоттки металл−DLC−полупроводник [8], в качестве антифрикционных и биологически инертных покрытий на имплантаты [9] и др.…”

Представлены результаты исследований оптических, электрических, механических свойств алмазоподобных углеродных пленок, полученных методом плазмохимического газофазного осаждения из смеси диборана и метана в различных пропорциях. При достижении пороговой концентрации (~ 12%) диборана в рабочей смеси, в структуре пленок начинают формироваться включения новой фазы. Это приводит к нелинейной зависимости внутренних напряжений и поверхностного сопротивления получаемых покрытий от состава смеси с минимальными значениями при концентрации диборана ~ 12%.
