In this study, we demonstrate the high response of 2D-(PEA)2PbBr4 perovskite of the horizontal vapor sensor was outstandingly more superior than 3D-MAPbBr3 perovskite. 2D transverse perovskite layer have the large surface-to-volume ratio and reactive surface, with the charge transfer mechanism, which was suitable for vapor sensing and trapping. Thus, 2D perovskite vapor sensors demonstrate the champion current response ratio R of 107.32 under the ethanol vapors, which was much faster than 3D perovskite (R = 2.92).<\/jats:p>","DOI":"10.3390\/s22218155","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T07:17:48Z","timestamp":1666768668000},"page":"8155","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Two-Dimensional (PEA)2PbBr4 Perovskites Sensors for Highly Sensitive Ethanol Vapor Detection"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8731-5157","authenticated-orcid":false,"given":"Ching-Ho","family":"Tien","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Lunghwa University of Science and Technology, Taoyuan 33306, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kuan-Lin","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Electro-Optical Engineering, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun-Cheng","family":"Tao","sequence":"additional","affiliation":[{"name":"Department of Electro-Optical Engineering, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhan-Qi","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Electro-Optical Engineering, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zi-Hao","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Electro-Optical Engineering, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5470-8491","authenticated-orcid":false,"given":"Lung-Chien","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Electro-Optical Engineering, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"605","DOI":"10.1007\/s40846-016-0164-6","article-title":"Significance of Exhaled Breath Test in Clinical Diagnosis: A Special Focus on The Detection of Diabetes Mellitus","volume":"36","author":"Das","year":"2016","journal-title":"J.
