To investigate multi-boson peaks (multi-BP), terahertz time-domain spectroscopy was performed on amorphous silicon monoxide (a-SiO), which…
Terahertz time-domain spectroscopy (THz-TDS) was performed on cellulose and paramylon ester to detect the boson peak…
Terahertz time-domain spectroscopy and low-frequency raman scattering were performed on polymethyl methacrylate to detect the boson…
For disordered systems, a universal excitation called boson peak appears in the terahertz range. In this…
