Short-range structure of proton-conducting BaM0.10Zr0.90O2.95 (M = Y, In, Sc and Ga) investigated with vibrational spectroscopy
The short-range structures of hydrated and dry samples of the proton-conducting, cubic-structured, acceptor-doped perovskites BaM0.10Zr0.90O2.95 (M=Y, In, Sc and Ga), and, for comparison, BaZrO3, have been investigated using infrared and Raman spectroscopy. The results show that the acceptor-doping leads to local structural distortions of the average cubic structure, most likely related to tilts o
