This comprehensive review examines the exceptional thermoelectric performance enhancements achieved in Pb_1-xSn_xTe systems through synergistic exploitation of their topological nature and advanced nanostructuring strategies. The critical composition range x = 0.35–0.5 represents a topological phase transition where band inversion creates protected surface states while simultaneously enabling optimal bulk electronic structure modification. Strategic band engineering approaches—including compositional tuning via Se/S alloying (achieving band convergence), resonant doping with Na/K/Cl (optimizing carrier concentration), and valley convergence mechanisms—enable precise electronic property control while preserving topological characteristics. Complementary nanostructuring methodologies through hierarchical architectures spanning atomic-scale defects to mesoscale precipitates (2–10 nm) successfully decouple electronic and thermal transport via selective phonon scattering mechanisms. The most effective optimization strategies combine L-Σ valence band convergence with controlled nanoprecipitate formation, achieving remarkable ZT values up to 1.9 at 773-823 K—representing 300–1200 % enhancement over pristine compounds. Critical analysis reveals that weak topological perturbations (≤5 % alloying) maximize performance by maintaining beneficial band dispersion characteristics, while excessive disruption degrades both surface states and bulk transport properties. These findings establish fundamental design principles for next-generation topological thermoelectrics: (1) maintaining crystalline mirror symmetries during processing, (2) optimizing grain sizes (80–120 nm) for surface state preservation, (3) achieving optimal band convergence without destroying topological protection, and (4) implementing hierarchical phonon scattering while preserving electrical percolation. This review synthesizes current understanding of topology-enhanced transport phenomena and provides comprehensive guidance for developing superior thermoelectric materials that harness quantum protection mechanisms for practical energy conversion applications.</div></div>","PeriodicalId":432,"journal":{"name":"Solid State Sciences","volume":"170 ","pages":"Article 108128"},"PeriodicalIF":3.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145517881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
