However, its high dark current has limited its application as a high-sensitivity photodetector at room temperature, particularly for the detection of low-energy photons. Our research proposes a new approach for overcoming this challenge by designing lattice antennas with an asymmetric structure for use in combination with high-quality monolayers of graphene. This configuration is capable of sensitive detection of low-energy photons. The results show that the graphene terahertz detector-based microstructure antenna has a responsivity of 29 V\u00b7W\u22121 at 0.12 THz, a fast response time of 7 \u03bcs, and a noise equivalent power of less than 8.5 pW\/Hz1\/2. These results provide a new strategy for the development of graphene array-based room-temperature terahertz photodetectors.<\/jats:p>","DOI":"10.3390\/s23063203","type":"journal-article","created":{"date-parts":[[2023,3,17]],"date-time":"2023-03-17T02:59:26Z","timestamp":1679021966000},"page":"3203","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Monolayer Graphene Terahertz Detector Integrated with Artificial Microstructure"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5105-467X","authenticated-orcid":false,"given":"Mengjie","family":"Jiang","sequence":"first","affiliation":[{"name":"State Key Laboratory for Modification of Chemical Fibers and Polymer Materials, Department of Optoelectronic Science and Engineering, Donghua University, Shanghai 201620, China"},{"name":"State Key Laboratory for Infrared, Physics Shanghai Institute of Technical Physics, Chinese Academy of Sciences, 500 Yu-tian Road, Shanghai 200083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaixuan","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Modification of Chemical Fibers and Polymer Materials, Department of Optoelectronic Science and Engineering, Donghua University, Shanghai 201620, China"},{"name":"State Key Laboratory for Infrared, Physics Shanghai Institute of Technical Physics, Chinese Academy of Sciences, 500 Yu-tian Road, Shanghai 200083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuyang","family":"Lv","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Modification of Chemical Fibers and Polymer Materials, Department of Optoelectronic Science and Engineering, Donghua University, Shanghai 201620, China"},{"name":"State Key Laboratory for Infrared, Physics Shanghai Institute of Technical Physics, Chinese Academy of Sciences, 500 Yu-tian Road, Shanghai 200083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Infrared, Physics Shanghai Institute of Technical Physics, Chinese Academy of Sciences, 500 Yu-tian Road, Shanghai 200083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Libo","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Infrared, Physics Shanghai Institute of Technical Physics, Chinese Academy of Sciences, 500 Yu-tian Road, Shanghai 200083, China"},{"name":"Hangzhou Institute for Advanced Study, College of Physics and Optoelectronic Engineering, University of Chinese Academy of Sciences, No. 1, Sub-Lane Xiangshan, Xihu District, Hangzhou 310024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Han","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Infrared, Physics Shanghai Institute of Technical Physics, Chinese Academy of Sciences, 500 Yu-tian Road, Shanghai 200083, China"},{"name":"Hangzhou Institute for Advanced Study, College of Physics and Optoelectronic Engineering, University of Chinese Academy of Sciences, No. 1, Sub-Lane Xiangshan, Xihu District, Hangzhou 310024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huaizhong","family":"Xing","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Modification of Chemical Fibers and Polymer Materials, Department of Optoelectronic Science and Engineering, Donghua University, Shanghai 201620, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26","DOI":"10.1038\/nmat708","article-title":"Materials for terahertz science and technology","volume":"1","author":"Ferguson","year":"2002","journal-title":"Nat.
