Schematic showing the multiple imaging and analytical signals available in STEM. Top right is a HAADF image of BiFeO 3 ; the brightest atom columns are Bi and the less bright ones Fe, which are seen displaced slightly to the right due to the ferroelectric polarization. The center image is a bright-field image showing O columns, below is a color composite EELS image of LaMnO 3 in which the Mn is shown in red, O in green, showing displacements due to octahedral rotations, and La in blue.
