“…The hardness and elastic modulus of MAC were experimentally reported to be proportional to the fraction of sp 3 orbitals, and it was proved by MD simulation (Figures 5c). [15,86] Since metalloid or metal doping (Si, [58,63] B 4 C, [54] Ag, [87,88] Cu, [87] Ti [59,60] ) in the a-C thin film significantly increased the hardness, the depth of indentation after the friction scratch test was much less in the Ti (9.75%)-doped a-C thin film. However, surface cracks and wear scars were prominent because the enhanced hardness lost the plasticity of the pristine a-C thin film.…”

“…Для того, чтобы установить, каким образом включения серебра оказывает влияние на соотношение sp 2и sp 3 -гибридизованных атомов углерода, были проанализированы спектры характеристических потерь энергии электронов. Согласно общепринятому описанию, встраивание серебра в углеродную структуру сопровождается обрывом углерод-углеродных связей, приводящим к перестройке sp 3 -гибридизованного углерода в sp 2 -гибридизацию [36]. По-видимому, результаты работы [10], показавшие, что взаимодействие серебра и углерода приводит к формированию не гексагональных графитовых кластеров, а цепочечных sp 2 -структур, свидетельствуют о том, что графитизация, вызванная воздействием серебра, в исследуемом случае в достаточной степени локализована.…”
