Description
Summary:Edge nanoimprint lithography is used to fabricating conducting polymer nanowires, which feature width can be as small as 2.5% of the original stamp. [Display omitted] In this paper, a convenient and universal strategy is reported to fabricate high-resolution conducting polymer nanowires, combining edge nanoimprinting with gas etching. Based on this method, 81.3nm polypyrrole nanowires were obtained, which is much smaller than the original cavity. The resulting conducting polymer nanowires exhibit representative ohmic behavior and excellent sensitivity to NH3. This method may potentially be used to construct other organic nanoelectronic devices.
