Fast Conductance Switching in Single-Crystal Organic Nanoneedles Prepared from an Interfacial Polymerization-Crystallization of 3,4-Ethylenedioxythiophene

摘要

Science at the nanoscale has been one of the most exciting areas of recent investigation, with activities that are of both fundamental and technological significance. New physical phenomena and revolutionary nanoeletronic devices based on novel nanomaterials are anticipated. Organic conjugated systems have been successfully applied to electronics because of their versatile electronic properties and their adaptability to a broad range of processing methods. However, the development of polymer electronics at the nanoscale is in its infancy. Here we report the first synthesis of polythiophene nanoneedles that exhibit fast, field-induced conductance switching in a single nanocrystalline element.
