Abstract

original image

The differential conductivity of the domains of a phase segregated diblock copolymer film, polystyrene-block-poly (ferrocenylethylmethylsilane) (PS-b-PFEMS), is described using conducting-probe atomic force microscopy. The schematic on the right depicts the experimental setup, and the image on the left is a representative current map of a 1 µm2 PS-b-PFEMS thin film on gold substrate, under an applied voltage bias of −9 V.
