| 英文摘要 | We report a definitive evidence that germanium isotope effect triggers a noticeable cage distortion in n-type Ba8Ga16Ge30 (BGG) with complete substitution of isotope Ge-76. Further extended X-ray absorption fine structure technique reflects a large disorder in the cages of the sample, although no accompanying obvious changing in distance of Ge-Ga/Ge is demonstrated. Hence, we suggest that the cumulative cage distortion originates from the variation of bond angle instead of bond length. Moreover, the intensive electron-phonon scattering is dominated by the isotope effect. These findings highlight atomic isotope engineering for modifying crystal structure and possibly even thermoelectric performance. |
