Research of the Impact of Silicon Doping with Holmium on its Structure and Properties Using Raman Scattering Spectroscopy Methods

East European Journal of Physics
Each crystal structure has its own phonon modes, which appear in the Raman spectrum of Raman scattering. In the case of silicon, phonon modes associated with the diamond structure of silicon can be detected. In a Raman spectrum, the position of the lines,
