- Abstract
- We report on a novel protocol for patterning the semiconducting polyaniline with an unprecedented areal patterning density exceeding 0.25 teradot/inch2. A simple two-step process is put forward to hierarchically build a large variety of tridimensional functional nanostructures on virtually any type of substrate. Using template confined growth through platinumcatalyzed electroless growth, highly-ordered arrays of distinct polyaniline nanowires are produced with a typical diameter of 15 nm and aspect ratio higher than 20. Up-scaling is straightforward. Complex three-dimensional structural control is achieved through a direct pattern transfer using a novel type of resist- and dose-modulated electron beamlithography. The method is scalable, provides a generic approach for nano- 200 nm 100 nm Figure 1: Transmission electron micrograph of a selfassembled fragment. Inset: Close-up on a single modulated nanopillar.

Nanoscale aspects of the growth mechanismare discussed and highly controllable, sub-picogram scale fabrication is emphasized. Bottom-up and top-down paradigms are converged to grow single nanoscale polyaniline elements with an unseen structural and positional control [1].
