“…Because TiS 2 -based layered sulfides are primarily composed of earth-abundant, low-toxicity, and light elements, they will pave the way for environment-friendly, cost-effective, and lightweight thermoelectric devices [29,30,39,40,41,42,43,44,45,46,47,56,57,58,59,60,61,62,63,64,65,66]. The two-dimensional crystal structure of these systems is a great example in which the thermoelectric performance can be improved through nanoblock integration and hierarchical architecturing.…”

“…One way to reduce κ lat is the intercalation of guest atoms and guest layers into the host TiS 2 layer [42,43,44,65,66]. For example, Cu intercalation reduces κ lat from ~2.0 W·K −1 ·m −1 for TiS 2 to ~1.7 W·K −1 ·m −1 for Cu 0.1 TiS 2 , and SnS intercalation dramatically reduces κ lat to ~1.0 W·K −1 ·m −1 for [SnS] 1.2 [TiS 2 ] 2 at 300 K (Figure 7a).…”

“…Miyazaki et al [81] have reported a significant variation in the c -axis depending on the ionic radius of the rare-earth element. Previous results have shown that NbS 2 [32,53,81,82], TaS 2 [83,84], and TiS 2 [42,43,65,66] sandwich structures show metallic conductivity, whereas CrS 2 [32,85] and VS 2 [78,85] sandwich structures show semiconducting properties. The crystal structure and physical properties of this misfit family were extensively studied in the 1990s [78]; however, not many reports on their thermoelectric properties exist to date.…”

Sulfides are promising candidates for environment-friendly and cost-effective thermoelectric materials. In this article, we review the recent progress in all-length-scale hierarchical architecturing for sulfides and chalcogenides, highlighting the key strategies used to enhance their thermoelectric performance. We primarily focus on TiS2-based layered sulfides, misfit layered sulfides, homologous chalcogenides, accordion-like layered Sn chalcogenides, and thermoelectric minerals. CS2 sulfurization is an appropriate method for preparing sulfide thermoelectric materials. At the atomic scale, the intercalation of guest atoms/layers into host crystal layers, crystal-structural evolution enabled by the homologous series, and low-energy atomic vibration effectively scatter phonons, resulting in a reduced lattice thermal conductivity. At the nanoscale, stacking faults further reduce the lattice thermal conductivity. At the microscale, the highly oriented microtexture allows high carrier mobility in the in-plane direction, leading to a high thermoelectric power factor.

Sr n+1 Ti n O 3n+1 (n = 1, 2,...n) Ruddlesden-Popper phase is a metal oxide compound with a layered structure consisting of SrTiO 3 perovskite layers and strontium oxide (SrO) layers, thus this material has a potential as termoeletrik compounds that could be developed as an alternative material for renewable energy. In this study, we examine one of the 3 parameters of termoelectric properties, namely the electrical conductivity. Sr n+1 Ti n O 3n+1 (n = 1 and 2) Ruddlesden-Popper phases were synthesized using molten salt method. The synthesis was carried out at 950 °C for 10 hours with a ratio of precursor and salt were 1: 0.5. Structural analysis by X-Ray Diffractometer (XRD) confirmed that all synthesized compounds formed Sr n+1 Ti n O 3n+1 (n = 1, and 2) Ruddlesden-Popper phase with the characteristic peaks at 2θ = 31 o , 32 o , and 46 o . The morphology analysis by Scanning Electron Microscope (SEM) showed that the particles have plate-shaped with crystallites size were 20 nm. The electrical properties were measured using LCR meter with the highest electrical conductivity of 2.25x10-7 S / cm which showed the semiconductors behaviour.
