Inside Front Cover: Differential Conductivity in Self-Assembled Nanodomains of a Diblock Copolymer Using Polystyrene-block-Poly(ferrocenylethylmethylsilane) (Adv. Mater. 10/2008)

The differential conductivity of the domains of a phase‐segregated diblock copolymer film, polystyrene‐block‐poly ferrocenylethylmethylsilane (PS‐b‐PFEMS), is investigated using conducting‐probe atomic force microscopy as reported by Gilbert Walker and co‐workers on p. 1989. Analysis of PFEMS regions show asymmetric I‐V behavior, and concomitant width increase with bias indicates filling of trap states. Here, the topography is shown to correlate with the current image when scanning with an applied voltage bias.
