Figure 4: Measurement and analysis of the conductivities for the LMO nanowires.
From: Suppressed phase transition and giant ionic conductivity in La2Mo2O9 nanowires
(a) Image of aligned wires placed on electrodes. (b) Schematic illustration of the configuration for the AC impedance spectroscopic measurements. (c) Arrhenius plots of the conductivities of LMO nanowires with various radii (made primarily by changing the salt-to-polymer ratio in the precursor solutions), together with the measured conductivities for corresponding bulk LMO. (d) Plot of ln(σ) versus 1/r for the nanowires (see Supplementary fig. S15 for the complete fitting with a model). Evidence of oxygen-ion conduction in LMO nanowires with an average diameter of 45 nm. (e) Conductivity of LMO nanowires versus oxygen partial pressure at 550 °C. (f) Conductivity of LMO nanowires versus humidity at various measuring temperatures.
