To achieve this objective, the first part presents a study of the conductivity evolution of these sensors, in order to find the optimal operating temperature and to improve the kinetics of adsorption of gas molecules on the surface of the thin layer. In a second step, we tried to develop a mathematical model that describes as closely as possible the electrical behavior of these sensors in order to simulate their operation and optimize their performances. Elovich models have been applied to both gas adsorption and desorption phases and have led to good similarities between theoretical and measured response curves.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords<\/strong> : Gas sensors ,\u00a0thin layer ,\u00a0phthalocyanine ,\u00a0conductivity , modeling.<\/p>\n<p style=\"text-align: justify;\">\n","protected":false},"excerpt":{"rendered":"<p>Num\u00e9ro de la revue:\u00a034 Auteurs: Amel Sahki, Allal Larbi &amp; Mohamed Cherif Boudiaf Laboratoire d&rsquo;Etudes et de Recherches en Instrumentation et en Communications de Annaba (L.E.R.I.C.A.), Universit\u00e9 Badji Mokhtar &#8211; Annaba, B.P.12, 23000 &#8211; Annaba, Alg\u00e9rie. \u00a0 &nbsp; T\u00e9l\u00e9charger l&rsquo;article &hellip; <a href=\"https:\/\/synthese.univ-annaba.dz\/?p=6687\">Lire la suite <span class=\"meta-nav\">&raquo;<\/span><\/a><\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1145],"tags":[1209,1206,1210,1208,1207],"class_list":["post-6687","post","type-post","status-publish","format-standard","hentry","category-synthese-n-34","tag-conductivity","tag-gas-sensors","tag-modeling","tag-phthalocyanine","tag-thin-layer"],"_links":{"self":[{"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/posts\/6687","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=6687"}],"version-history":[{"count":4,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/posts\/6687\/revisions"}],"predecessor-version":[{"id":6799,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/posts\/6687\/revisions\/6799"}],"wp:attachment":[{"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=6687"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=6687"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=6687"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
