Article Synopsis
- One-dimensional Haldane gap materials, like rare earth barium chain nickelates, exhibit strong spin antiferromagnetic properties and unique structures that make them interesting for thermoelectric applications.
- The material CaBaGdNiO shows impressive Seebeck coefficients of 140-280 μV K at high temperatures, maintained even with significant acceptor-substitution levels due to low dimensionality and electronic correlations.
- Despite low thermal conductivities of around 1.5 W m K, ideal for thermoelectrics, the electrical conductivity of these materials is still insufficient, highlighting the need to improve electronic band structures and microstructural features to boost charge carrier mobility.
