Book Description
Thermoelectric devices convert a heat flux directly into electrical power. They afford opportunities to achieve efficiency savings in a variety of applications, through the conversion of otherwise waste heat into useful electrical energy. Operated in reverse mode, they provide effective thermal management in areas ranging from cooling of electronic components to battery conditioning in electric vehicles. Implementation of thermoelectric technology requires materials with improved performance and stability, containing readily-available and inexpensive elements. A range of thermoelectric materials for use in different temperature regimes has emerged. Knowledge of the complex relationship between composition, structure and physical properties is central to understanding the performance of these advanced materials. This book provides both an introduction to the field of thermoelectrics and a survey of the state-of-the-art. Chapters review the important new families of advanced materials that have emerged and taken the field beyond traditional thermoelectric materials such as Bi2Te3, PbTe and SiGe. The emphasis is on the relationship between chemical composition, structure over a range of length scales and the physical properties that underlie performance. Edited by a leader in the field, and with contributions from global experts, Inorganic Thermoelectric Materials serves as an introduction to thermoelectric materials and is accessible to advanced undergraduates and postgraduates, as well as experienced researchers

Book Description
The focus of this thesis work is the exploratory preparation of novel chalcogenides as potential thermoelectric materials and the analyses of their physical properties. A thermoelectric material is capable of converting heat to electricity or vice versa. Usually, narrow band gap semiconductors are good candidates for thermoelectric applications, because such materials have large Seebeck coefficient, reasonably high electrical conductivity and low thermal conductivity. In this work, two different systems were studied, intermetallic pseudo hollandite structures and layered CdI2 type structures. In the large family of pseudo hollandite systems, we mainly focused on thallium systems in which the solid solution TlxCr5Se8 and TlCr5Se8-xTex have been synthesized. In CdI2 structures, we focused our investigation on transition metal selenides for their rather semiconducting properties. Therefore we embarked on the systematic study of AgCrSe2, TiS2 and TiSe2. In addition, the effect on physical properties using different intercalated elements (Ag and Cu) in TiSe2 chalcogenides were studied. All these samples are prepared by the solid state reaction. The purity of the samples was confirmed by powder X-ray diffraction data, physical and thermal properties were measured on Spark Plasma Sintered (SPS) samples. Low thermal conductivity as well as competitive power factors was observed in these chalcogenides. The highest zT of 0.54 is achieved in titanium dichalcogenides for the composition of Cu0.05TiS1.5Se0.5 at 700K. Our results show that these structures are potential for future thermoelectric materials research.

Book Description
Chalcogenide crystals are a unique class of materials very different from semiconductors or metallic alloys. They have many practical applications in the civil and military fields, especially in relation to their electronic, optical, and mechanical properties for energy conversion as thermoelectric materials and in environmental materials. Thermoelectric materials can be used to generate electricity from the temperature gradient based on the Seebeck effect and based on the Peltier effect they can be used in cooling applications. However, the fundamental understanding of the electronic structure and other physical properties of the chalcogenides is rather scattered and incomplete because they are much less systemically studied. This work provides a comprehensive study of many physical properties for large number of chalcogenide crystals. This work is mainly divided into two main parts: chapter 3 and chapter 4. In the first part of this work (chapter 3), we present a detailed study using first-principles calculations on the electronic structure, interatomic bonding, optical, and mechanical properties for 131 chalcogenide crystals. This part itself is divided into two main sections: section 3.1 and section 3.2 in chapter 3. Section 3.1 is for the first 32 crystals of 131 crystals, while section 3.2 is for the remaining 99 crystals. Based on this large database, we are able to identify some new and conspicuous observations to reach some useful conclusions related to the chemical composition of the chalcogenide compounds and their complex interatomic interactions. Moreover, the total bond order density (TBOD) is used as a single quantum mechanical metric to characterize the internal cohesion of these crystals enabling us to correlate them with the calculated properties, especially their mechanical properties. Finally, generalization of the observed trends and empirical rules can be extended to much larger classes of ternary and quaternary chalcogenide crystals and glasses so far unexplored. In the second part of this work (chapter 4), using density functional theory and semiclassical Boltzmann theory, we have computed the Seebeck coefficient, electrical conductivity, electronic thermal conductivity, power factor, and figure of merit of 30 chalcogenide crystals. VASP and Quantum Espresso packages are used to relax the crystal structures, calculate the electronic properties, and locate the Fermi level. The transport properties are then calculated using the BoltTraP code. The 30 crystals are divided into two groups. The first group has four crystals with quaternary composition (A2BCQ4) (A = Tl; B = Cd, Hg; C = Si, Ge, Sn; Q = S, Se, Te). The second group contains 26 crystals with the ternary composition (A'B'Q2) (A' = Ag, Cu, Au, Na; B' = B, Al, Ga, In; Q = S, Se, Te). Among these 30 chalcogenide crystals, the results for 11 crystals: Tl2CdGeSe4, Tl2CdSnSe4, Tl2HgSiSe4, Tl2HgSnS4, AuBSe2, AuBTe2, AuAlTe2, AuGaTe2, AuInTe2, AgAlSe2, and AgAlTe2 are revealed for the first time. In addition, temperature dependent transport properties of pure and doped AgSbSe2 and AgSbTe2 crystals with dopant compositions of AgSb0.94Cd0.06Te2 and AgSbTe1.85Se0.15 were explored. These results provide a large database for bulk chalcogenides crucial for a wide range of potential applications in renewable energy fields.
