In the present work, the synthesis of MoS2/Si coatings was conducted to study the effect of Si on the microstructure of the MoS2/Si coatings and their tribological behavior. With the adoption of advanced characterization methods, the results reveal that the introduction of Si plays significant roles in determining the morphologies and structures of the MoS2/Si coatings. The results demonstrate that the increase of Si content can cause the changes of the coatings from a typical porous with columnar morphology to a non-porous with featureless morphology, while as the Si content continues to increase up to a much higher content (i.e., 17.3 at.%) the coatings with composite structure change to the a multilayer nanostructure. The tribological tests results point out that the MoS 2 /Si coatings with a composite structure perform better tribological properties as the content of Si rises from 0 to 14.7 at.%, owing to the combination of the increase in hardness and the oxygen gettering effect of Si. However, the MoS2/Si coatings with a multilayer nanostructure formed under a much high Si content (17.3 at.% Si) display poor tribological properties as the excessive Si inhibits the formation of the transfer film upon severe three-body abrasive wear.

This paper reviews the feasibility of the state-of-the-art electrical techniques adopted from Si technology for characterization of SiC MOS devices. The inability of these conventional characterization techniques to correctly evaluate the trap capture cross section and field-effect mobility in SiC MOS devices are investigated and explained. As near-interface traps (NITs) are an important cause of field-effect mobility degradation in SiC MOS devices, which is different from the impact of interface traps in Si devices, these characterization techniques are unable to produce meaningful results. Therefore, special care is required when measuring these NITs in SiC MOS devices. Due to the quantum confinement effect, the NITs located above the conduction band edge are able to capture and release channel electrons from the conduction band via tunnelling. Recent characterization techniques, specifically designed for SiC MOS devices, measure the NITs above the bottom of conduction band and consider the quantum confinement effect to find the energy position of the NITs. These recent characterization techniques are presented in the later part of the paper.
