| 研究成果の概要 |
The PI has performed temperature-dependent THz measurements. Quasi-harmonic calculations have been performed to qualitatively explain the temperature-dependent frequency shifts for a few THz peaks. The correlation between the quasi-harmonicity and the nature of the THz modes has been discussed.

| 研究成果の学術的意義や社会的意義 |
This research work gives an insight into the anharmonicity of THz modes, which may help to understand many related macroscopic properties such as thermal (or negative) expansion and heat conduction.
