Multidimensional microscopic characteristics (images and spatial profiles) of the organic heterostructure blend made of fullerene C 60 and poly[(2,7-(9,9-dihexa)fluorene)-co-(1,4-(2,5-didecylaminoketo) phenylene)]: (a) tapping-mode AFM surface morphology, (b) KFM surface potential, (c) micro-Raman intensity at 1468 cm-1, (d) micro-Raman intensity at 1400 cm-1, and (e) local conductivity as measured by CS-AFM (negative bias voltage applied on the sample). Positions of the profiles in the images are indicated by the dashed lines and arrows.
