Fig. 1: Room-temperature electrical and proton conductivities of mixed protonic-electronic conductors including this study (Ni-BAND).
From: Proton-electron coupling and mixed conductivity in a hydrogen-bonded coordination polymer
Proton conductivities were measured under humid (RHโ>โ90%) conditions, except for the radical crystals (measured in vacuum). Electrical conductivities were obtained under humid conditions, except for Ni-BAND (dry) and Zn-HHTP-H2O (RH 30%). Dashed line indicates equal proton and electron conductivities.
