  text: Copper chalcogenides offer high charge mobility and low lattice thermal conductivity
    but suffer from structural instability due to dynamic Cu+ migration. Here, we
    report a colloidal hot-injection synthesis of ternary cesium copper selenide (CsCu5Se3)
    nanocrystals (NCs), achieving precise control over phase, size, and morphology
    through tailored precursor-ligand modulation. This strategy enabled systematic
    exploration of stable and metastable Cs–Cu–Se phases and mechanistic investigation
    of nucleation and growth, providing insight into phase modulation and dimensional
    control at the nanoscale. CsCu5Se3 NCs exhibit low lattice thermal conductivity
    (∼0.5 Wm–1K–1) and an experimental zT of 0.27 at 718 K. Complementary first-principles
    calculations, consistent with experimental electronic and optical responses, predict
    a zT of 1.05 at 1000 K. These findings elucidate the formation dynamics of CsCu5Se3
    and establish ABZ (A = alkali, B = metal, Z = chalcogen) NCs as tunable platforms
    for advanced functional applications.

  text: Silver selenide (Ag2Se) is a promising near-room-temperature thermoelectric
    material, but its narrow stoichiometric window and β–α phase transition complicate
    reproducible microstructure control. Here, we present a mismatch-assisted microstructure
    engineering strategy in which Ag2Se particles are treated with polyanionic ZnSe
    complexes and consolidated through the β–α transition to introduce ZnSe nanoprecipitates,
    Ag2Se/ZnSe interfaces, and local strain fields. The crystallographic mismatch
    between ZnSe and Ag2Se, together with the Zn2+/Ag+ size difference, amplifies
    phase-transition-induced deformation and promotes high-density dislocations with
    periodic strain modulations. This defect architecture suppresses grain coarsening,
    removes excess Ag, limits Ag-interstitial formation, and reduces lattice thermal
    conductivity through lattice softening and multiscale phonon scattering. Ag2Se–4%ZnSe
    nanocomposites achieve a peak zTmax of 1.13 at 369 K and a zTavg of 1.08 from
    300 to 380 K, demonstrating mismatch-driven defect engineering through the β–α
    phase transition as a route for optimizing Ag2Se-based thermoelectrics.

  text: Alkali salts are widely used in solution processing, yet the corresponding
    cations are often assumed to remain in the liquid phase. Here, we show that alkali
    ions introduced during the solution synthesis of SnSe are retained through particle
    isolation and continue to influence the material during subsequent thermal processing,
    where they shape the evolution of the final polycrystalline material. Different
    SnSe powders were prepared using Li+, Na+, and K+ precursors, as well as tetramethylammonium
    (TMA+) precursors as a nonalkali reference for comparison, and all samples were
    consolidated under identical conditions. Although all three alkali ions were found
    in the matrix, at grain boundaries, and in segregated nanoscale regions, they
    partitioned differently and resulted in distinct grain sizes, defect distributions,
    and therefore transport properties. Li induced the strongest grain size heterogeneity
    and the lowest energy barriers, Na the best overall balance between carrier concentration
    and mobility, and K the broadest alkali-rich grain boundary regions along with
    the strongest interfacial penalty to charge carrier transport. These results show
    that residual alkali ions are not just remnants of solution synthesis but active
    determinants of microstructure and thermoelectric performance in SnSe.
