Carbon-paste nanocomposites as unconventional gate electrodes for electrolyte-gated organic field-effect transistors

Nanocomposite carbon-paste electrodes (NC-CPEs) have been investigated for the first time in electrolyte-gated organic field-effect transistors (EGOFETs) as a replacement of conventional metal gate electrodes, using carbon nanotubes (CNTs) as a model carbon filler. Interestingly, the electrical prop...

Accordingly, NC-CPEs have been demonstrated to be a potential alternative to metal gate electrodes for the development of a new generation of highly sensitive carbon-based EGOFET bio-sensors. 22019-01-0120192019-01-01Articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/223741https://dx.doi.org/urn:doi:10.1039/c9tc04929kreponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengEuropean Commission https://doi.org/10.13039/501100000780 306826Agencia Estatal de Investigación https://doi.org/10.13039/501100011033 CTQ2016-80030-RAgencia Estatal de Investigación https://doi.org/10.13039/501100011033 MAT2016-77852-C2-1-RAgència de Gestió d'Ajuts Universitaris i de Recerca https://doi.org/10.13039/501100003030 2017/SGR-918Agència de Gestió d'Ajuts Universitaris i de Recerca https://doi.org/10.13039/501100003030 2017/SGR-1277Ministerio de Economía y Competitividad https://doi.org/10.13039/501100003329 SEV-2015-0496Ministerio de Ciencia e Innovación https://doi.org/10.13039/501100004837 RYC-2017-22910open accesshttp://purl.org/coar/access_right/c_abf2Aquest document està subjecte a una llicència d'ús Creative Commons.
