These characteristics, in addition to the fact that CNTs experience changes in their electrical conductance when exposed to different gases, make them appropriate candidates for use in sensing\/measuring applications such as gas detection devices. In this research, a model for a Field Effect Transistor (FET)-based structure has been developed as a platform for a gas detection sensor in which the CNT conductance change resulting from the chemical reaction between NH3 and CNT has been employed to model the sensing mechanism with proposed sensing parameters. The research implements the same FET-based structure as in the work of Peng et al. on nanotube-based NH3 gas detection. With respect to this conductance change, the I\u2013V characteristic of the CNT is investigated. Finally, a comparative study shows satisfactory agreement between the proposed model and the experimental data from the mentioned research.<\/jats:p>","DOI":"10.3390\/s140305502","type":"journal-article","created":{"date-parts":[[2014,3,20]],"date-time":"2014-03-20T12:06:02Z","timestamp":1395317162000},"page":"5502-5515","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["Analytical Calculation of Sensing Parameters on Carbon Nanotube Based Gas Sensors"],"prefix":"10.3390","volume":"14","author":[{"given":"Elnaz","family":"Akbari","sequence":"first","affiliation":[{"name":"Centre for Artificial Intelligence and Robotics (CAIRO), Universiti Teknologi Malaysia,  Kuala Lumpur 54100, Malaysia"},{"name":"Institute of High Voltage & High Current, Faculty of Electrical Engineering, Universiti Teknologi Malaysia, Johor Bahru 81310, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zolkafle","family":"Buntat","sequence":"additional","affiliation":[{"name":"Institute of High Voltage & High Current, Faculty of Electrical Engineering, Universiti Teknologi Malaysia, Johor Bahru 81310, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohd","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Institute of High Voltage & High Current, Faculty of Electrical Engineering, Universiti Teknologi Malaysia, Johor Bahru 81310, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aria","family":"Enzevaee","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Universiti Teknologi Malaysia, Johor Bahru 81310, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rubiyah","family":"Yousof","sequence":"additional","affiliation":[{"name":"Centre for Artificial Intelligence and Robotics (CAIRO), Universiti Teknologi Malaysia,  Kuala Lumpur 54100, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Syed","family":"Iqbal","sequence":"additional","affiliation":[{"name":"Institute of High Voltage & High Current, Faculty of Electrical Engineering, Universiti Teknologi Malaysia, Johor Bahru 81310, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad","family":"Ahmadi","sequence":"additional","affiliation":[{"name":"Computational Nanoelectronic Research Group Faculty of Electrical Engineering,  Universiti Teknologi Malaysia, Johor Bahru 81310, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad","family":"Sidik","sequence":"additional","affiliation":[{"name":"Institute of High Voltage & High Current, Faculty of Electrical Engineering, Universiti Teknologi Malaysia, Johor Bahru 81310, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hediyeh","family":"Karimi","sequence":"additional","affiliation":[{"name":"Centre for Artificial Intelligence and Robotics (CAIRO), Universiti Teknologi Malaysia,  Kuala Lumpur 54100, Malaysia"},{"name":"Malaysia -Japan International Institute of Technology (MJIIT), Universiti Teknologi Malaysia, Kuala Lumpur 54100, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2014,3,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2423","DOI":"10.1109\/JSEN.2013.2256124","article-title":"Carbon nanotubes with adsorbed Au for sensing gas","volume":"13","author":"Lin","year":"2013","journal-title":"IEEE Sens.
