Abstract Thermoelectric Mg 3+ δ (Sb, Bi) 2 Zintls have attracted significant attention because of their high‐performing, eco‐friendly, and cost‐effective features, but thermoelectric properties still need improvement for application to practical devices. Here an outstanding ZT ≈1.87 at 773 K a high average ≈1.2 in n‐type Y‐doped 3.2 Sb 1.5 Bi 0.49 Se 0.01 are reported, both which rank as top values among the reported literature. First‐principles calculations indicate that substituting site...
Abstract As cathode catalysts for lithium–oxygen batteries (LOBs), 2D materials are attracting significant attention due to their layered structures, tunable surface chemistry, and unique electronic states. However, catalytic anisotropy, particularly the poor capability of van der Waals forces contained in stack edge planes, has suppressed enhancement LOB performance as catalysts. Here, an ion‐intercalation strategy is proposed diminish anisotropy materials. Ag ions successfully intercalated...
By the fine manipulation of exceptional long-range germanium-telluride (Ge─Te) bonding through charge transfer engineering, we have achieved thermoelectric (TE) and mechanical properties in lead-free GeTe.

Recently, researchers spare no efforts to fabricate desirable vanadium dioxide (VO2) film which provides simultaneously high luminous transmittance and outstanding solar modulation ability, yet progress towards the optimization of one aspect always comes at expense other. Our research devotes finding a reproducible economic solution-processed strategy for fabricating VO2-SiO2 composite films, with aim boosting performance both aspects. Compare VO2 film, an improvement 18.9% (from 29.6%...

It is well known that sodium at grain boundaries (GBs) increases the photovoltaic efficiencies of CuInSe 2 and Cu ZnSnS 4 significantly. However, mechanism how influences GBs still unknown. Based on recently proposed self‐passivation rule, it found dangling bonds in can completely be saturated through doping Na, thus GB states are successfully passivated. shown Na easily incorporate into with very low formation energy. Although also passivate states, requires a copper rich condition which,...
