Bi2 Te3 -related alloys dominate the commercial thermoelectric market, but layered crystal structure leads to dissociation and intrinsic brittle fracture, especially for single crystals that may worsen practical efficiency. In this work, point defect configuration by S/Te/I defects engineering is engaged boost mechanical properties of n-type alloy, which, coupled with p-type BiSbTe, shows a competitive conversion efficiency fabricated module. First, as S alloying suppresses BiTe, antisite...
Abstract The emerged strategy of entropy engineering provides new ideas for realizing high‐performance thermoelectric materials, but it is still much unresolved how to achieve delicate trade‐off between the carrier mobility m H and lattice thermal conductivity κ ph in taking advantage configurational Δ S . Herein, significant advances ultralow yet decent a medium‐entropy system well‐designed (Pb, Ge, Sb, Cd) co‐alloyed SnTe reported. Moreover, co‐alloying also optimizes concentration n...
Engineering the electronic band structures upon doping is crucial to improve thermoelectric performance of materials. Understanding how dopants influence states near Fermi level thus a prerequisite precisely tune structures. Here, we demonstrate that Sn-s in SnTe contribute density at top valence band. This consequence half-filled p-p σ-bond (metavalent bonding) and its resulting symmetry orbital phases maximum (L point Brillouin zone). insight provides recipe for identifying superior...

In this study, we report the achievement of exceptional thermoelectric performance high plasticity stable Cu<sub>2</sub>Se/SnSe composites. A novel matrix plainification strategy was employed to eliminate lattice vacancies within Cu<sub>2</sub>Se composites, resulting a marked improvement carrier mobility. This increase mobility corresponds substantial...
<title>Abstract</title> Thermoelectric materials allow direct conversion between heat and electricity may be useful for power generation or solid-state refrigeration. However, improving thermoelectric performance is challenging because of the strong coupling electrical thermal transport properties. We demonstrate a new super-gravity-field re-melting fabrication technology that synergistically optimizes performance. Using super-gravity field, brittle (Bi,Sb)<sub>2</sub>Te<sub>3</sub> alloy...
Carbon fiber-reinforced composite stringers, which support aircraft skins in resisting tensile, compressive, and shear loads, are widely used structures. These structures play a crucial role enhancing the performance safety of structural integration aircrafts. To better understand load-bearing capacity stringer structures, this study developed novel model to complex failure load transmission behavior T800/3900S-2B skin-stringer under compressive loading. Compression strength tests were...
Discrepancies between experimental and theoretical results in the study of thermoelectric generators (TEGs) have been a major long-standing problem technology. In this Letter, we report that, besides interfacial resistance, inevitable heat leap caused by Peltier effect is main factor affecting conversion efficiency TEGs. fact, proven to an impact approximately 10% on common addition, enhance formula for maximum with from classical expression allow prediction performance advanced materials...
Zone-melted Bi2Te3-based alloys are the only commercially available thermoelectric (TE) materials, but they suffer from mediocre figure of merit (ZT) values and brittleness. In this work, we prepared Bi0.48Sb1.52Te3 sintered samples using a hot-pressing method added tiny AgCuTe to improve comprehensive properties. Because carrier concentration is boosted by addition, bipolar effect at higher temperature explicitly suppressed power factor also improved in broad scope. Simultaneously, κlat...
Bismuth-telluride-based thermoelectric materials have been applied in active room-temperature cooling, but the mediocre ZT value of ∼1.0 limits (TE) device's conversion efficiency and determines its application. In this work, we show obviously improved properties p-type Bi0.5Sb1.5Te3 by Cu8GeSe6 composite. The addition effectively boosts carrier concentration thus bipolar thermal conductivity as temperature is elevated. With content 0.08 wt %, hole reaches 5.0 × 1019 cm-3 corresponding...
The thermoelectric properties of GeTe (300 ∼ 700 K) are significantly improved, leading to a conversion efficiency 8.6% with T c = 300 K and h K.
In the mid-temperature region, SnTe is a promising substitute for PbTe, whereas thermoelectric (TE) property of pristine severely limited by good thermal conductivity and inferior Seebeck coefficient. this research, we synergistically manipulate interdependent TE parameters SnTe-AgBiTe2 alloys Mn doping to increase ZT value. The AgBiTe2 alloying found greatly reduce electrical electronic contribution transport reducing carrier mobility, while obviously improves coefficient effectively...
