Using self-consistent phonon calculations, we reveal that strong anharmonicity and twofold rattling modes of Cs2SnI6 induce an ultralow thermal conductivity of 0.11 W m−1 K−1 at 300 K, rarely expected of simple and single-crystalline solids.

We investigated the thermoelectric performance of metal phosphides MP2 (M = Co, Rh and Ir), such as Seebeck coefficient, electrical conductivity, and lattice and electron thermal conductivity, using the density functional theory calculations.

Organic spacer cations with aromatic rings are more favourable for enhancing the moisture stability of FAPbI3 3D/2D interfaces than those with aliphatic chains. The anilinium-based system shows the highest resistance to water penetration.
