By constructing composite structures of various gas-sensitive materials, more-efficient and sensitive gas sensors can be further developed. After graphene is compounded with WS2, the composite material can improve the gas detection performance. In this work, the adsorption energy and the electronic properties of a graphene\/WS2 structure were calculated by first-principles before and after adsorption of NH3. The calculation results indicate that the bandgap of the material was appreciably reduced after NH3 was adsorbed. In addition, a graphene\/WS2 gas sensor was prepared. The response of the sensor to NH3 at a concentration of 100 ppm was 2.42% and 1.73% at 30 \u00b0C and 60 \u00b0C, respectively. Combining simulation with experiment, it is feasible to use graphene composite WS2 to detect NH3, which provides a new idea for applications of graphene and other composite materials in gas sensing.<\/jats:p>","DOI":"10.3390\/s22228672","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T02:11:15Z","timestamp":1668046275000},"page":"8672","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Gas-Sensitive Characteristics of Graphene Composite Tungsten Disulfide to Ammonia"],"prefix":"10.3390","volume":"22","author":[{"given":"Fei","family":"Zhao","sequence":"first","affiliation":[{"name":"Institute of Electrical and Information Engineering, Zhenjiang College, Zhenjiang 212100, China"},{"name":"Zhenjiang Key Laboratory of Advanced Sensing Materials and Devices, School of Mechanical Engineering, Jiangsu University, Zhenjiang 212013, China"}]},{"given":"Zhongxue","family":"Li","sequence":"additional","affiliation":[{"name":"Zhenjiang Key Laboratory of Advanced Sensing Materials and Devices, School of Mechanical Engineering, Jiangsu University, Zhenjiang 212013, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6087-4891","authenticated-orcid":false,"given":"Yongzhong","family":"Fu","sequence":"additional","affiliation":[{"name":"Zhenjiang Key Laboratory of Advanced Sensing Materials and Devices, School of Mechanical Engineering, Jiangsu University, Zhenjiang 212013, China"}]},{"given":"Quan","family":"Wang","sequence":"additional","affiliation":[{"name":"Zhenjiang Key Laboratory of Advanced Sensing Materials and Devices, School of Mechanical Engineering, Jiangsu University, Zhenjiang 212013, China"},{"name":"State Key Laboratory of Transducer Technology, Chinese Academy of Sciences, Shanghai 200050, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"129240","DOI":"10.1016\/j.snb.2020.129240","article-title":"FET-type gas sensors: A review","volume":"330","author":"Hong","year":"2020","journal-title":"Sens.
