- •
n-type CaxCo4Sb12 was synthesized with high pressure synthesis method.
- •
Maximal filling fraction of Ca was substantially increased due to high pressure.
- •
Power factor as high as 5400 μWm−1K−2 was reached in Ca0.31Co4Sb12.
- •
The highest ZT of 1.15 was achieved in the optimal Ca0.31Co4Sb12 at 840 K.
