Abstract

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.
