Here, BiTe is investigated as a representative system in which the effects of spin\u2013orbit coupling (SOC) and higher-order phonon anharmonicity are examined separately. Angle-resolved photoemission spectroscopy and density functional theory confirm that SOC is essential to the topological electronic structure, while machine-learning moment-tensor potentials enable a quantitative assessment of its influence on phonon transport. Including SOC slightly increases the lattice thermal conductivity by weakening low-frequency phonon scattering. Temperature-dependent Raman spectroscopy reveals mode-dependent higher-order anharmonicity, and explicit transport calculations show that four-phonon scattering substantially suppresses thermal conductivity. These findings demonstrate that both SOC and higher-order phonon scattering should be considered for a reliable description of heat transport in BiTe and provide broader insight into thermal transport in topological materials containing heavy elements.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6c01704","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T13:12:58Z","timestamp":1785849178000},"page":"8762-8768","source":"Crossref","is-referenced-by-count":0,"title":["Relativistic\nand Anharmonic Contributions to Low Thermal\nConductivity in Topological Material BiTe"],"prefix":"10.1021","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8235-8289","authenticated-orcid":true,"given":"Peng","family":"Wu","sequence":"first","affiliation":[{"name":"North China Electric Power University , , , ,","place":["Hebei, Baoding, People\u2019s Republic of China, 071003"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Zhang","sequence":"additional","affiliation":[{"name":"North China Electric Power University , , , ,","place":["Hebei, Baoding, People\u2019s Republic of China, 071003"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4924-1927","authenticated-orcid":true,"given":"Lidong","family":"Zhang","sequence":"additional","affiliation":[{"name":"University of Science and Technology of China , , , ,","place":["Hefei, Anhui, China, 230029"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Sun","sequence":"additional","affiliation":[{"name":"The University of Tokyo , , ,","place":["Tokyo, Japan, 113-0032"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhikang","family":"Cui","sequence":"additional","affiliation":[{"name":"Beihang University , , , ,","place":["Hefei, Anhui, People\u2019s Republic of China, 230013"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weijian","family":"Wang","sequence":"additional","affiliation":[{"name":"North China Electric Power University , , , ,","place":["Hebei, Baoding, People\u2019s Republic of China, 071003"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengtai","family":"Liu","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences , , ,","place":["Shanghai, China, 201210"]},{"name":"Chinese Academy of Sciences , , ,","place":["Shanghai, China, 200050"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ranran","family":"Zhang","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences , , ,","place":["Hefei, China, 230031"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhanfeng","family":"Liu","sequence":"additional","affiliation":[{"name":"University of Science and Technology of China , , , ,","place":["Hefei, Anhui, China, 230029"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-4214-2018","authenticated-orcid":true,"given":"Tongrui","family":"Li","sequence":"additional","affiliation":[{"name":"University of Science and Technology of China , , , ,","place":["Hefei, Anhui, China, 230029"]},{"name":"University of Science and Technology of China , , ,","place":["Hefei, China, 230026"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,28]]},"reference":[{"key":"2026080609093876900_cit1","doi-asserted-by":"publisher","first-page":"634","DOI":"10.1126\/science.1156446","article-title":"High-thermoelectric\nperformance of nanostructured bismuth antimony telluride bulk alloys","volume":"320","author":"Poudel","year":"2008","journal-title":"Science"},{"key":"2026080609093876900_cit2","doi-asserted-by":"publisher","first-page":"1045","DOI":"10.1103\/RevModPhys.84.1045","article-title":"Colloquium: Phononics: Manipulating heat flow with electronic analogs\nand beyond","volume":"84","author":"Li","year":"2012","journal-title":"Rev.
