Enhanced thermoelectric properties of p-type Ag2Te by Cu substitution
Literature Information
Hangtian Zhu, Jun Luo, Huaizhou Zhao, Jingkui Liang
Enhanced thermoelectric properties of p-type Ag2Te have been achieved through partial substitution of Ag by Cu. The (Ag0.985−xCux)2Te alloy becomes a β-Ag2Te single-phase solid solution above the structural transition temperature, which is a superionic conductor with highly mobile ions and low lattice thermal conductivity. The substitution of Cu for Ag increases the band gap and hole concentration of the solid solution, leading to not only a suppressed bipolar effect but also greatly improved electrical transport properties. Meanwhile, a periodically modulated layered nanostructure is observed in (Ag0.985−xCux)2Te alloys, which may be attributed to the Cu substitution. As a result, the electrical conductivity increases with the Cu content, and the Seebeck coefficient at high temperature is substantially improved. Both the carrier and lattice thermal conductivities are decreased because of the suppressed bipolar effect and enhanced phonon scattering, respectively. The modified electrical and thermal transport properties enable a maximum ZT value of 1.39 for the sample with x = 0.3, indicating the great potential of superionic conductors as novel thermoelectric materials.

Journal of Materials Chemistry A

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive.
