Here, nonequilibrium molecular dynamics simulations are employed to investigate the thermal transport behaviors of WSSe\/MoS2 and WSSe\/MoSe2 lateral heterostructures. Unlike the commonly assumed flat interface, both heterostructures spontaneously form an intrinsically curved interface after relaxation, introducing a unique structural feature for phonon transport. The armchair interface exhibits higher interfacial thermal conductance than the zigzag counterpart due to stronger phonon coupling. Furthermore, external strain can effectively regulate thermal transport through the competition between interface flattening and phonon scattering, while increasing temperature enhances thermal conductance by activating low-frequency phonons. In contrast, vacancy defects also significantly suppress heat transfer by disrupting interfacial bonding. This work reveals the critical role of intrinsic interface curvature in phonon-mediated thermal transport and provides a new strategy for designing high-performance thermal management materials based on Janus heterostructures for advanced energy conversion and storage technologies.<\/jats:p>","DOI":"10.3390\/molecules31162876","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T08:08:41Z","timestamp":1787040521000},"page":"2876","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Intrinsic Curvature-Induced Regulation of Interfacial Thermal Transport in Janus TMD Heterostructures"],"prefix":"10.3390","volume":"31","author":[{"given":"Lixia","family":"Shi","sequence":"first","affiliation":[{"name":"School of Intelligent Manufacturing, Changzhou Vocational Institute of Textile and Garment, Changzhou 213164, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liqi","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electronic Engineering, Nanjing Forestry University, Nanjing 210037, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianping","family":"Li","sequence":"additional","affiliation":[{"name":"School of Automotive & Transportation Engineering, Shenzhen Polytechnic University, Shenzhen 518055, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8367","DOI":"10.1038\/ncomms9367","article-title":"Femtosecond structural transformation of phase-change materials far from equilibrium monitored by coherent phonons","volume":"6","author":"Hase","year":"2015","journal-title":"Nat.
