Fig. 3: Influence of ion polarization power/polarizability on modulus.

Percentage change in E from CR-AFM (contact resonance) (a, b) and NI (nano-indenter) (c, d) between dry and humidity-exposed crystals, as function of X-site anion polarizability (a), (c), and as function of polarity of A-site cation (b), (d). Error bars are computed from the relative error of the quotient, using standard deviation of individual values.
