Optical conductivity of rattling phonons in type-I clathrate Ba $_{8}$ Ga $_{16}$ Ge $_{30}$

T. Mori, S. Goshima, K. Iwamoto +9

A series of infrared-active optical phonons have been detected in type-I clathrate Ba $_{8}$ Ga $_{16}$ Ge $_{30}$ by terahertz time-domain spectroscopy. The conductivity spectra with the…
