The device adopts a three-layer configuration consisting of a MoS2\/VO2 composite plane\u2013SiO2 dielectric\u2013Au reflector layer. Unlike conventional symmetric structures, which are limited by selection rules and symmetry-protected dark modes that hinder the excitation of higher-order resonances, this design effectively breaks structural symmetry protection through geometric asymmetry. This induces strong mode hybridization between originally orthogonal dark and bright modes, enabling broadband high absorption exceeding 96.7% across the 1.88\u20133.52 THz frequency range (61% RBW). Notably, the device demonstrates synergistic tuning advantages: the macroscopic on\/off switching of broadband absorption characteristics via the phase transition of VO2, combined with fine blind-spot compensation and enhancement in absorption peaks using the electrical tunability of MoS2. Furthermore, thanks to its sub-wavelength unit cell design, the structure maintains excellent performance stability over a wide incident angle range from 0\u00b0 to 60\u00b0. This study reveals a synergistic enhancement mechanism combining the asymmetric unit cell and hybrid materials, providing a systematic physical solution for resolving the trade-off between bandwidth extension and dynamic reconfigurability.<\/jats:p>","DOI":"10.3390\/ma19143133","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T15:17:52Z","timestamp":1784647072000},"page":"3133","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Synergistic Thermal\u2013Electrical Modulation of Broadband Terahertz Absorption via Asymmetric MoS2\/VO2 Hybrid Metasurfaces"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-9127-0122","authenticated-orcid":false,"given":"Xiaoyue","family":"Lu","sequence":"first","affiliation":[{"name":"School of Optoelectronic Science and Intelligent Instruments, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianbin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Science and Intelligent Instruments, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shihan","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Science and Intelligent Instruments, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiyu","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Science and Intelligent Instruments, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"220701","DOI":"10.1063\/5.0272428","article-title":"Unlocking Terahertz technology with machine learning: A comprehensive review","volume":"137","author":"Cacciari","year":"2025","journal-title":"J.
