Tuning of the ionic conductivity of Ba <sub>7</sub> Nb <sub>4</sub> MoO <sub>20</sub> by pressure: a neutron diffraction and atomistic modelling study
Pressure is used to tune the crystal structure and the ionic conductivity of the dual ion conductor Ba 7 Nb 4 MoO 20 . Increasing pressure results in a reduction in the fraction of MO 4 tetrahedra within the P–L layer and a decrease in oxide-ion transport.
