Abstract

We introduce Sb2Si2Te6 as a high-performance thermoelectric material. Single-crystal X-ray diffraction analysis indicates that Sb2Si2Te6 has a layered two-dimensional structure with Sb3+ cations and [Si2Te6](6) units as building blocks adopting the Fe2P2Se6 structure type. Sb2Si2Te6 is a direct-band-gap semiconductor with valence-band maximum and conduction-band minimum at the Z point in the ...
