Differential Conductivity in Self-Assembled Nanodomains of a Diblock Copolymer Using Polystyrene-block-Poly(ferrocenylethylmethylsilane)

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.
