Charging Rate

Charging rate image of a polymer blend film. AFM height image of a 50:50 film of F8BT/PFB spin coated from
xylenes (left). The recessed domains are enriched in PFB (film thickness: 90nm). (Right) EFM photoinduced
charging rate map generated by plotting the inverse exponential time constant for photoinduced charging at each
point shown on left image. The dark rings indicate regions of slower charging. Imaged with the MFP-3D AFM.
