CVD graphene was transferred using Polyurethane as sacrifice layer with low contamination and defect-free results. An atmospheric plasma etching system was used to homogeneously induce defects on the sensor\u2019s active area, as investigated through Raman spectroscopy. Device sensing properties were significantly enhanced for greater defect density for both <jats:italic>NH<\/jats:italic><jats:sub>3<\/jats:sub> and <jats:italic>NO<\/jats:italic><jats:sub>2<\/jats:sub>. The modified sensors were submitted to different concentrations of both target gas to assess detection limits and overall behavior. It was revealed that defective CVD graphene devices possess sensitivity up to ppm range with linear dependence in the range of values measured. The fabricated sensors presented little to no signal degradation after months of atmospheric exposure.<\/jats:p>","DOI":"10.1155\/2019\/5492583","type":"journal-article","created":{"date-parts":[[2019,11,4]],"date-time":"2019-11-04T19:14:20Z","timestamp":1572894860000},"page":"1-7","source":"Crossref","is-referenced-by-count":8,"title":["Plasma-Treated CVD Graphene Gas Sensor Performance in Environmental Condition: The Role of Defects on Sensitivity"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4903-6306","authenticated-orcid":true,"given":"Gil","family":"Capote Mastrapa","sequence":"first","affiliation":[{"name":"Brazilian Center for Research in Physics, Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando Lazaro","family":"Freire","sequence":"additional","affiliation":[{"name":"Pontifical Catholic University of Rio de Janeiro, Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1038\/nmat1967"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.snb.2015.04.062"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1007\/s40820-015-0073-1"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1126\/science.1171245"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.scib.2017.07.005"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/S0925-4005(97)00230-X"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.mseb.2017.12.036"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2015.02.002"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201102663"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevB.77.125416"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1039\/C5CP04422G"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1088\/1361-6528\/aa8611"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1038\/nnano.2013.46"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1021\/nl300901a"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/5492583.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/5492583.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/5492583.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,11,4]],"date-time":"2019-11-04T19:14:24Z","timestamp":1572894864000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2019\/5492583\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,11,4]]},"references-count":14,"alternative-id":["5492583","5492583"],"URL":"https:\/\/doi.org\/10.1155\/2019\/5492583","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2019,11,4]]}}}
