Then, let us try to apply the q-BWF to a specific case, that of the Raman LO mode band of a material which possesses remarkable properties, such as a high thermal conductivity , that is, the Silicon Carbide. Data are obtained from the Raman Open Database, a database developed in the framework of the project SOLSA H2020 (El Mendili et al., 2019). In the file at the web page , it is told that the Raman spectrum is related to a 6H-SiC structure, sampled from a terrestrial moissanite, locality at 150 km NW from Izmir, Turkey.
