The proposed framework provides distributions of internal resistance and interfacial capacitance and tracks their evolution during electrical cycling. The FORC results reveal a gradual reduction in the overall switching density accompanied by a narrowing of the coercive-voltage distribution and a shift of the internal-bias distribution toward zero, indicating a selective suppression of switching events under extreme local conditions. In addition, the average internal resistance exhibits a clear correlation with leakage current, while the interfacial capacitance decreases monotonically with cycling, which is interpreted as an increase in the effective oxide thickness. This purely electrical analysis provides quantitative insight into fatigue-induced inhomogeneous degradation in PZT thin-film capacitors and can be extended to other ferroelectric material systems.</div></div>","PeriodicalId":11037,"journal":{"name":"Current Applied Physics","volume":"85 ","pages":"Pages 1-7"},"PeriodicalIF":3.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145996245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A noticeable improvement in the LSPR peak is also observed with an increase in the dielectric function of the medium. Moreover, reducing the distance between nanoparticles enhances the localized surface plasmon resonance, which is a result of plasmonic coupling occurring between the adjacent nanoparticles. The extinction, absorption, and scattering optical responses depend on the direction of polarized light. A noticeable increase in the magnitude of the localized surface plasmon resonance, shifting to the near infrared, has been observed in the longitudinal polarization compared to the transverse polarization.
