How It Compares
Within the bismuth chalcogenide thermoelectrics class.
While classic thermoelectric materials like Bi2Te3 and Sb2Te3 are widely recognized for their high performance, KSbSe2 offers a distinct structural alternative within the bismuth chalcogenide class. Unlike the binary systems such as Sb2Se3 or Bi2Se3, the inclusion of potassium in KSbSe2 introduces unique lattice dynamics that differentiate its transport properties from those of more traditional compounds like AgSbTe2 or Ge2Sb2Te5.
