摘要: Abstract Surface profile images from La2O3 and La2CuO4 have been obtained using high resolution electron microscopy. A surface layer of the C-form about 1 nm in thickness coating bulk A-form movement atomic columns within this were observed; these two structural forms being intergrown with (001) plane parallel to (111) C-form. On (113) a crystal, single having different arrangement that crystal was visible, displacement some La cations on proven by image simulation. La2CuO4, re-arrangement also observed.
