摘要
We present the results of low-temperature (similar to 5 to 20 K) specific-heat measurements performed in numerous oxide glass systems. These results allow us to elucidate the impact of the system or component on the excess specific heat, which when plotted on C-p/T-3 vs T appears as a broad band known as the boson peak (BP). By integrating our experimental results with the data of Richet [Physica B 404, 3799 (2009); J. Chem. Phys. 136, 034703 (2012)], we demonstrate a strong negative correlation between the BP amplitude and its maximum temperature. We also describe the BP characteristics of multicomponent systems based on different binary systems in silicate glasses.
