摘要: Abstract Barium titanate is the main constituent of PTC materials and their electric properties are sensitive to microstructure defects, in atomic scale, that significantly affected by processing parameters. The barium doped with yttrium was investigated using topographic images obtained AFM contact mode. showed effect large grains double twins at different (1 1 1) planes.
