Recently, disorder engineering has emerged as an effective strategy to regulate the local coordination environment and stabilize the oxygen redox of LLOs. Herein, we confirm the existence of intrinsic intralayer Li/Mn disorder within the Li2MnO3 domains, which can be classified into local Li-excess and TM-excess configurations derived from the initial Li-rich framework. Furthermore, DFT calculations suggest complementary local roles for the different disordered configurations: Li-excess domains promote oxygen redox activity, whereas TM-excess domains reinforce TM–O bonding and stabilize the framework against irreversible degradation. Consequently, M-LLO containing the coupled disordered configurations promotes more reversible anionic redox, suppresses irreversible oxygen release and transition-metal migration, and thereby delivers improved electrochemical stability. This work provides new insights into the role of intrinsic disorder regulation in Li-rich layered cathodes.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"64 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While effective cavity-polariton formation emerges via the self-hybridization of ultrahigh oscillator strength excitons with a thin slab photonic mode, the absence of external mirrors facilitates spectroscopic investigation of these polaritons via cathodoluminescence (CL) on length scales inaccessible to optical excitation. This direct access allows us to precisely chart the polariton landscape with nanometric resolution, and probe polariton interference phenomena. Our finding highlights that coherent polariton transport follows the C2v symmetry of CrSBr, highly directional transport along the a-axis, while no coherent features are found along the b-axis. By extending CL spectroscopy to strongly anisotropic cavity polaritons, our work establishes this technique as a powerful tool to probe highly directional expansion and relaxation phenomena on the nanoscale, paving the way for investigating complex polaritonic landscapes in asymmetric systems.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"44 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149359317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose an in-plane heterostructure architecture that integrates molecular transport, confinement, and surface-enhanced Raman scattering (SERS) readout to enable deterministic and repeated interrogation of individual biomolecules. Using all-atom molecular dynamics coupled with nanoplasmonic simulations, we show that the heterostructure can actively guide molecules into and through a localized sensing region while constraining their conformational and translational dynamics. Simulated SERS signatures discriminate single-stranded DNA sequences with resolution approaching the single-nucleobase scale and further suggest the feasibility of distinguishing polyglutamine tracts of different lengths. Importantly, the in-plane geometry allows molecules to be controllably transported back and forth across the sensing region, providing a route to repeated measurements of the same molecule rather than relying on stochastic single-pass translocation. These results suggest a strategy for improving the accuracy and reproducibility of nanopore-based biomolecular sensing.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"64 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149359320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
