A and B site doping of a phonon-glass perovskite oxide thermoelectric

By tuning the A site cation size it is possible to control the degree of octahedral distortion and ultimately structural symmetry in the new perovskite solid solution La 0.5 Na 0.5− x K x TiO 3 , affording a rhombohedral-to-cubic transition as x increases above 0.4. The La 3+ and K + cations are dis...
