Thermoelectric performance can be largely enhanced by forming solid solutions and biaxial strain.
How to further improve the thermoelectric performance in Cu3SbSe4-based materials after optimizing its carrier concentration is a difficult issue. The present study attempts address issue by investigating of Cu3SbSe4 Sn and La codoping, all samples were obtained using microwave-assisted hydrothermal synthesis method followed with spark plasma sintering (SPS) process. First, series Cu3Sb1–xSnxSe4 (x = 0–0.03) compounds have been synthesized, hole obviously increased increasing content. In...
Abstract Semiconducting manganese ditelluride (MnTe2) crystalizes in a high symmetry cubic structure with sufficient band gap and consists of nontoxic elements only, therefore is focused on this work for its potential thermoelectric applications. This material intrinsically comes very low hole concentration 1019 cm−3, which can be successfully increased to 4 × 1020 cm−3 through Ag-doping at Mn site. Such broad carrier enables an effective optimization power factor, the doping process...
N-Type Mg3Sb2-based Zintl compounds have recently been discovered to be a promising class of thermoelectric materials. Effective n-type dopants are crucial for realizing high performance. Here, using first-principles defect calculations, we investigate that Tm and Ce effective in Mg3Sb2 explain why conduction can successfully achieved by simple doping without extra Mg. Under Mg-rich conditions, the maximal achievable free carrier concentrations substitution on Mg sites at 750 K exceed 1020...
Abstract Efficient and stable photocathodes with versatility are of significance in photoassisted lithium-ion batteries (PLIBs), while there is always a request on fast carrier transport electrochemical active photocathodes. Present work proposes general approach creating bulk heterojunction to boost the mobility by simply laser assisted embedding plasmonic nanocrystals. When employed PLIBs, it was found effective for synchronously enhanced photocharge separation light charging process....

Recent years have witnessed the chalcopyrite compound CuGaTe2 receiving widespread attention as a promising thermoelectric material. In work, we calculated band structure of Zn substitution at Ga site and found that element can effectively adjust degeneracy tetragonal distortion parameters CuGaTe2. By doping with different contents ZnTe, it is discovered ZnGa– point defects formed by CuGaTe2–ZnTe concrete solutions increase carrier concentration material significantly. Meanwhile, strongly...
In order to study the mechanical performance of self-compacting reinforced concrete beam with recycled coarse aggregates, and gravel were taken as aggregates particle size from 50 to150mm, two groups specimen beams made. After seven days, their bending strength tested using method one-third point loaded simple on testing machine. The results showed that are bonded closely concrete, its bond is good; Compared ordinary beam, it shows a smaller stiffness bigger mid-span deflection. addition,...
