Vector AFM of BST Film

BST film with vector PFM overlaid on AFM topography, 1µm scan. The color wheel permits identification of the
local orientation of the polarization. Regions colored as cyan (darker blue/green) possess polarizations
which are oriented predominantly normal to the plane of the film, whereas regions that appear magenta-blue
or light green possess polarizations which are oriented predominantly within the plane of the film. The intensity
of the color map denotes the magnitude of the response. Imaged with the MFP-3D AFM.
