The designed logarithmic antenna acts as an optical coupling structure to effectively localize the incident terahertz waves at the source end, thus forming a temperature gradient in the device channel and inducing the thermoelectric terahertz response. At zero bias, the device has a high photoresponsivity of 1.54 A\/W, a noise equivalent power of 19.8 pW\/Hz1\/2, and a response time of 900 ns at 105 GHz. Through qualitative analysis of the response mechanism of graphene PTE devices, we find that the electrode-induced doping of graphene channel near the metal-graphene contacts play a key role in the terahertz PTE response. This work provides an effective way to realize high sensitivity terahertz detectors at room temperature.<\/jats:p>","DOI":"10.3390\/s23063249","type":"journal-article","created":{"date-parts":[[2023,3,20]],"date-time":"2023-03-20T03:30:31Z","timestamp":1679283031000},"page":"3249","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Sensitive Room-Temperature Graphene Photothermoelectric Terahertz Detector Based on Asymmetric Antenna Coupling Structure"],"prefix":"10.3390","volume":"23","author":[{"given":"Liang","family":"Hong","sequence":"first","affiliation":[{"name":"Terahertz Technology Innovation Research Institute, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Lanxia","family":"Wang","sequence":"additional","affiliation":[{"name":"Terahertz Technology Innovation Research Institute, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Miao","family":"Cai","sequence":"additional","affiliation":[{"name":"Terahertz Technology Innovation Research Institute, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Yifan","family":"Yao","sequence":"additional","affiliation":[{"name":"Terahertz Technology Innovation Research Institute, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Xuguang","family":"Guo","sequence":"additional","affiliation":[{"name":"Terahertz Technology Innovation Research Institute, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Yiming","family":"Zhu","sequence":"additional","affiliation":[{"name":"Terahertz Technology Innovation Research Institute, University of Shanghai for Science and Technology, Shanghai 200093, China"},{"name":"Shanghai Institute of Intelligent Science and Technology, Tongji University, Shanghai 200092, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1016\/j.dit.2013.03.009","article-title":"Terahertz Technology and Its Applications","volume":"5","author":"Pawar","year":"2013","journal-title":"Drug Invent.
