Abstract Effects of humidity on domain switching behaviors in BaTiO3 single crystals under electric field were investigated by polarized light microscopy (PLM). It was found that the humidity has different effect on different domain configurations. The low humidity has no effect on both a-b domain configuration and b-c domain configuration under fields. However, the high humidity can promote b domain switch to c domain under electric fields. The effects were explained by different adsorption of polar H2O molecules on different domain areas in humidity conditions.

Key words: Domain switching Humidity BaTiO3 single crystals sustained external field
