"spin-entropy impacts 2D magnet's thermoelectric properties... thermoelectrics devices efficiency increased by (1) increased entropy (disorder), (2) In 2D magnetic materials, magnetic order, generating spin-entropy contribution, (3) number of layers charge carrier accesses in 2D layered material, producing additional layer entropy... 2D antiferromagnet CrSBr... thermoelectric response increases with temperature as electrons and spins mobilize, reaching local maximum around magnetic phase transition Néel temperature
