The study investigated different compositions of sodium silicate glasses using terahertz time-domain spectroscopy, low-frequency Raman scattering, and low-temperature specific heat measurements. The researchers successfully detected the behavior of the boson peak (BP) in all measurements, and found that the BP frequency is insensitive to Na2O composition. Additionally, comparing the Raman spectrum and terahertz absorption spectrum confirmed that the BP vibration mode is a combination of different fundamental vibration modes.
