“…To obtain a hydrogen-terminated surface, the activation of hydrogen atoms is performed usually by hot filament (HF) process [ 18 , 19 , 20 ], microwave (MW) process [ 21 , 22 , 23 ] or radio frequency (RF) process [ 22 ]. Recently, it has also been shown that contact electrification-induced hydrogenation method results in effective hydrogen termination of nanodiamond surface [ 24 ].…”

Extensive Raman spectroscopy studies combined with scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) measurements were performed to investigate structural and chemical changes in diamond layers deposited by chemical vapour deposition (CVD) upon post-growth treatment with hydrogen. The aim of this study is to characterize the changes in micro-structural properties of diamond layers with different grain sizes and different contents of sp2 carbon phase. Hydrogenation or oxidization of diamond layer surface is often performed to modify its properties; however, it can also strongly affect the surface structure. In this study, the impact of hydrogenation on the structure of diamond layer surface and its chemical composition is investigated. Owing to their polycrystalline nature, the structural properties of CVD diamond layers can strongly differ within the same layer. Therefore, in this project, in order to compare the results before and after hydrogen treatment, the diamond layers are subjected to Raman spectroscopy studies in the vicinity of a T-shape marker fabricated on the surface of each diamond layer studied.
