Rogers, John A. Kim, Ji Hun 2013-02-03T19:45:46Z 2013-02-03T19:45:46Z 2015-02-03T11:00:53Z 2012-12 2013-02-03T19:45:46Z 2012-12 Among the remarkable variety of semiconducting nanomaterials that have been discovered, single walled carbon nanotubes (SWNTs) have properties that make them uniquely well suited for high-performance carbon nanotube field-effect transistors (CNTFETs). The most advanced opportunities, however, demand optimized properties of semiconducting SWNTs in horizontal arrays. Here, we present strategies that optimize CNTFETs by using an array-based metallic nanotube removal process with joule heating induced thermocapillary flow in thin organic layers. Detailed experimental studies reveal the selective removal of metallic SWNTs. We provide statistically significant demonstrations to prove the effectiveness and selectivity of this approach and to study the underlying physics of joule-induced thermocapillary flow, and we present several demonstrations of electronic devices based on aligned arrays (both purified and unpurified) along with detailed characterization of their performance.
