“…As already mentioned, the focus of this work is on a comparison and evaluation of the power factor and the figure of merit zT . For a more detailed discussion of the physical properties of thermoelectric oxides, e.g., for oxide-based materials [ 9 , 36 , 49 ] or BiCuSeO [ 49 , 50 , 51 ], the reader is referred to other review articles.…”

Energy harvesting with thermoelectric materials has been investigated with increasing attention over recent decades. However, the vast number of various material classes makes it difficult to maintain an overview of the best candidates. Thus, we revitalize Ioffe plots as a useful tool for making the thermoelectric properties of a material obvious and easily comparable. These plots enable us to consider not only the efficiency of the material by the figure of merit zT but also the power factor and entropy conductivity as separate parameters. This is especially important for high-temperature applications, where a critical look at the impact of the power factor and thermal conductivity is mandatory. Thus, this review focuses on material classes for high-temperature applications and emphasizes the best candidates within the material classes of oxides, oxyselenides, Zintl phases, half-Heusler compounds, and SiGe alloys. An overall comparison between these material classes with respect to either a high efficiency or a high power output is discussed.

PbTe is a typical intermediate-temperature thermoelectric material, which has undergone extensive developments and achieved excellent high thermoelectric performance. In this perspective we summarized several strategies that were successfully applied in PbTe-based thermoelectric materials through manipulating charge and phonon transports, such as optimizing carrier density to tune Fermi level, tailoring band structure to enhance effective mass, and designing all-scale hierarchical architectures to suppress phonon propagation. Meanwhile, due to the different features of conduction and valence bands, we separately introduced the approaches to enhance performance of p-type and n-type PbTe. In p-type PbTe, the strategies of band convergence, band alignment and density of state (DOS) distortion are more effective to achieve high electrical transport properties. By contrast, flattening conduction bands and introducing deep impurity level are more suitable for n-type PbTe. Lastly, several potential strategies were proposed to further improve the thermoelectric performance of PbTe-based materials, which might be extended to other thermoelectric systems.

“…В последнее время медные оксиселениды привлекают значительное внимание научного сообщества благодаря их низкой теплопроводности и относительно высокому значению термоэдс. Более того, исследования оксиселенидов BiCuSeO показали, что эти материалы обладают высокой термоэлектрической эффективностью при температурах до 923 K [1][2][3]. Медные оксиселениды BiCuSeO относятся к семейству оксихалькогенидов LnCuChO (где Ln -ион редкоземельного элемента или висмута, Ch -ион группы халькогенидов или пниктогенов), кристаллическая решетка которых соответствует структурному типу ZrSiCuAs (пространственная группа P4/nmm) и состоит из расположенных вдоль оси c тетрагональной кристаллической ячейки слоев (Cu 2 Ch 2 ) 2− и (Ln 2 O 2 ) 2+ (рис.…”

The results of investigating the thermoelectric properties of the bulk р -type oxyselenides Bi_1 –_ x Pr_ x CuSeO ( x = 0, 0.04, 0.08) and Bi_0.96La_0.04CuSeO obtained by the solid-state reaction technique are presented. The temperature dependences of the thermopower, electrical resistivity, and thermal conductivity are measured at temperatures from room temperature to 800 K. Over the whole temperature range, a decrease in the electrical resistivity and thermopower is observed with increasing substitution level, while the thermal conductivity is almost unaffected by the substitution of rare-earth elements for bismuth. Despite the nominal valence of Bi, La, and Pr being the same, the replacement of bismuth by rare-earth ions leads to an increase in the charge-carrier concentration, which may be caused by a difference in the electronic configurations of ions, resulting in a shift of the Fermi level to the valence band.
