Chirality-induced spin selectivity has emerged as a powerful strategy for generating spin-polarized currents without magnetic materials. Here, we demonstrate that controlled intercalation of chiral L-cysteine molecules into exfoliated MoS2 nanosheets at two different concentrations enables deformation-driven tuning of chirality and spin polarization. Notably, circular dichroism measurements show inversion of chiroptical response with molecular loading, which directly correlates with the sign\u00a0and magnitude of spin polarization measured by using scanning tunneling spectroscopy. Density functional theory calculations reveal the structural-deformation dependence of the bandgap width and of the spin\u2013orbit coupling splitting. The results establish a clear structure\u2013chirality\u2013spin relationship, where stacking-induced symmetry breaking governs spin-selective transport. This work provides a mechanistic framework for engineering chiral two-dimensional materials with tunable spin functionality for next-generation spintronic applications.<\/jats:p>","DOI":"10.1063\/5.0346826","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T17:54:04Z","timestamp":1786989244000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Deformation-driven modulation of chirality and spin polarization in L-cysteine intercalated MoS2 nanosheets: A mechanistic approach to chirality-induced spin selectivity in two-dimensional material"],"prefix":"10.1063","volume":"165","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-1012-7013","authenticated-orcid":false,"given":"Mahe Taiba","family":"Hussain","sequence":"first","affiliation":[{"name":"Department of Applied Physics and Materials Engineering, National Institute of Technology 1 , Patna 800005,","place":["India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0253-1425","authenticated-orcid":false,"given":"Subrata","family":"Majumder","sequence":"additional","affiliation":[{"name":"Department of Applied Physics and Materials Engineering, National Institute of Technology 1 , Patna 800005,","place":["India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matej","family":"Komelj","sequence":"additional","affiliation":[{"name":"Jo\u017eef Stefan Institute 2 , Jamova cesta 39, SI-1000 Ljubljana,","place":["Slovenia"]},{"name":"Faculty of Mathematics and Physics, University of Ljubljana 3 , Jadranska ulica 19, SI-1000 Ljubljana,","place":["Slovenia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,8,17]]},"reference":[{"issue":"9\u201310","key":"2026081713535717600_c1","doi-asserted-by":"publisher","first-page":"395","DOI":"10.1002\/andp.201400137","article-title":"Transition-metal dichalcogenides for spintronic applications","volume":"526","year":"2014","journal-title":"Ann.
