Abstract Semiconducting and non-semiconducting ceramics BaTiO3 are studied by SEAM technique. The thermal wave coupling mechanism plays an important role in the origins of image contrast in SEAM of semiconducting ceramics BaTiO, because the doping impurities screen and decrease the effect of electronic property changes on the electron acoustic image contrast. The differences of electronic property decide the origins of image contrast in SEAM of non-semiconducting ceramics BaTiO3.
