Lattice thermal conductivity reduction in Ca 3 AlSb 3 and Ca 5 Al 2 Sb 6 by manipulating the covalent tetrahedral chain

Understanding the structural and physical origins of low thermal conductivity is critical to improving and designing efficient thermoelectric materials. For two distinct Zintl Ca-Al-Sb compounds with different stoichiometric ratios (Ca AlSb and Ca Al Sb ), experimental measurements suggest the low l...
