English abstract:
The intermetallic compound CeRu4Sn6 has been tentatively classified as
Kondo insulator. This class of material, especially non-cubic representatives,
is not yet fully understood. Here we report thermopower measurements on
single-crystalline CeRu4Sn6 between 2 K and 650 K, along the main crystallographic
directions. Large positive thermopower is observed in the directions
along which the hybridization is strong and a Kondo insulating gap forms. A
negative contribution to the thermopower dominates for the crystallographic c
axis where hybridization is weak and metallicity prevails.
Keywords:
Kondo insulator, thermopower, power factor, anisotropic hybridization
