How It Compares
Within the bismuth chalcogenide thermoelectrics class.
Within the broader class of bismuth and antimony chalcogenides, K3SbSe3 occupies a distinct niche compared to standard binary thermoelectrics like Bi2Te3 or Sb2Se3. While many members of this class are well-known for their optimized thermoelectric performance, K3SbSe3 offers a different structural motif, providing a valuable contrast to the commonly studied KSbSe2. Its stability and semiconducting nature make it a compelling subject for comparative studies aimed at understanding how alkali metal incorporation influences the electronic transport properties of these sophisticated material systems.
