However, a direct and definitive proof of the absence of inversion symmetry in this material, a prerequisite for the existence of Weyl Fermions, has so far remained evasive. Herein, an unambiguous identification of the broken inversion symmetry in TaIrTe<jats:sub>4<\/jats:sub> is established using angle\u2010resolved polarized Raman spectroscopy. Combining with high\u2010resolution transmission electron microscopy, an efficient and nondestructive recipe to determine the exact crystallographic orientation of TaIrTe<jats:sub>4<\/jats:sub> crystals is demonstrated. Such technique could be extended to the fast identification and characterization of other type\u2010II Weyl fermions candidates. A surprisingly strong in\u2010plane electrical anisotropy in TaIrTe<jats:sub>4<\/jats:sub> thin flakes is also revealed, up to 200% at 10 K, which is the strongest known electrical anisotropy for materials with comparable carrier density, notably in such good metals as copper and silver.<\/jats:p>","DOI":"10.1002\/adma.201706402","type":"journal-article","created":{"date-parts":[[2018,5,8]],"date-time":"2018-05-08T02:35:36Z","timestamp":1525746936000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":84,"title":["Raman Signatures of Broken Inversion Symmetry and In\u2010Plane Anisotropy in Type\u2010II Weyl Semimetal Candidate TaIrTe<sub>4<\/sub>"],"prefix":"10.1002","volume":"30","author":[{"given":"Yinan","family":"Liu","sequence":"first","affiliation":[{"name":"International Center for Quantum Materials School of Physics Peking University  No. 5 Yiheyuan Road Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiangqiang","family":"Gu","sequence":"additional","affiliation":[{"name":"International Center for Quantum Materials School of Physics Peking University  No. 5 Yiheyuan Road Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Peng","sequence":"additional","affiliation":[{"name":"Centre for Programmed Materials School of Materials Science and Engineering Nanyang Technological University  Singapore 639798 Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaomian","family":"Qi","sequence":"additional","affiliation":[{"name":"International Center for Quantum Materials School of Physics Peking University  No. 5 Yiheyuan Road Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Na","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Molecular Engineering Peking University  No. 5 Yiheyuan Road Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinong","family":"Zhang","sequence":"additional","affiliation":[{"name":"International Center for Quantum Materials School of Physics Peking University  No. 5 Yiheyuan Road Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiumei","family":"Ma","sequence":"additional","affiliation":[{"name":"Electron Microscopy Laboratory School of Physics Peking University  Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Zhu","sequence":"additional","affiliation":[{"name":"Electron Microscopy Laboratory School of Physics Peking University  Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lianming","family":"Tong","sequence":"additional","affiliation":[{"name":"College of Chemistry and Molecular Engineering Peking University  No. 5 Yiheyuan Road Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji","family":"Feng","sequence":"additional","affiliation":[{"name":"International Center for Quantum Materials School of Physics Peking University  No. 5 Yiheyuan Road Beijing 100871 China"},{"name":"CAS Center for Excellence in Topological Quantum Computation University of Chinese Academy of Sciences  Beijing 100190 China"},{"name":"Collaborative Innovation Center of Quantum Matter  Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zheng","family":"Liu","sequence":"additional","affiliation":[{"name":"Centre for Programmed Materials School of Materials Science and Engineering Nanyang Technological University  Singapore 639798 Singapore"},{"name":"NOVITAS Nanoelectronics Centre of Excellence School of Electrical and Electronic Engineering Nanyang Technological University  Singapore 639798 Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9485-1759","authenticated-orcid":false,"given":"Jian\u2010Hao","family":"Chen","sequence":"additional","affiliation":[{"name":"International Center for Quantum Materials School of Physics Peking University  No. 5 Yiheyuan Road Beijing 100871 China"},{"name":"Collaborative Innovation Center of Quantum Matter  Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,5,7]]},"reference":[{"key":"e_1_2_5_1_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.107.127205"},{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevB.83.205101"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature13763"},{"key":"e_1_2_5_3_2","first-page":"031023","volume":"5","author":"Huang X.","year":"2015","journal-title":"Phys.
