Engineering a Correlated Narrow-Gap Semiconductor: Effects of Ga Substitution in EuZn $_{2}$ P $_{2}$

M. Dutra, E. Marulanda, G. G. Vasques +11

The effect of Ga substitution on the electronic, magnetic, and low-energy responses of the Zintl phase EuZn $_{2}$ P $_{2}$ is investigated by electrical transport, electron spin resonanc…

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…
