It is difficult to detect 𝛽-SiC using micro-Raman scattering, if it is surrounded by carbon medium. Here, 𝛽-SiC is identified in the presence of a relatable surrounding diamond medium using subtle, but discernible Raman surface phonons. In this study, diamond/𝛽-SiC nanocomposite thin film system is considered in which nanosized 𝛽-SiC crystallites are surrounded by a relatable nanodiamond medium that leads to the appearance of a weak Raman surface phonon band at about 855 cm-1. Change in the nature of the surrounding material structure and its volume content when relatable, will affect the resultant Raman response of 𝛽-SiC phase as seen in the present case of diamond/𝛽-SiC nanocomposite thin films.
