Thermoelectric materials can be utilized to generate electricity from a temperature gradient, thereby recycling the nowadays abundant waste heat, as well as for cooling applications by creating a temperature gradient from electricity. The former is based on the Seebeck effect, and the latter on the ...
In the 600–800 K temperature regime, heavily doped lead chalcogenides (PbTe, PbSe, PbS) are the leading materials for thermoelectric power generation [163–165]. PbTe was first discovered in 1845 as the rare mineral altaite [166], while the more abundant galena (PbS) has been the main...
Recently, entropy engineering has been used as a novel strategy to optimize the electrical and thermal transport properties of TE materials18,19,20. By increasing element species, the mixing entropy in a material system increases quickly, and high-entropy materials with over five principal elements ...
Thermoelectric (TE) materials can realize significant energy savings by generating electricity from untapped waste heat. However, the coupling of the thermoelectric parameters, unfortunately, limits their efficiency and practical applications. Metal chalcogenide nanosheets have recently attracted considerable atten...
Two-segment ingots have been obtained using melt compositions corresponding to ternary layered compounds in the PbTe-Bi 2 Te 3 and PbTe-Sb 2 Te 3 systems, with (Bi 2 Te 3 ) 1 x y (Sb 2 Te 3 ) x (Sb 2 Se 3 ) y solid solutions as seed materials. Seeded growth of the ternary...
Two-dimensional (2D) materials with multiphase, multielement crystals such as transition metal chalcogenides (TMCs) (based on V, Cr, Mn, Fe, Cd, Pt and Pd) and transition metal phosphorous chalcogenides (TMPCs) offer a unique platform to explore novel ph

In subject area: Materials Science Chalcogenide materials are compounds typically consisting of one or more chalcogen elements (sulfur, selenium, or tellurium, but excluding oxygen) which are covalently bonded to elements from neighboring groups in the periodic table such as As, Ge, Ga, Sb, etc....
Chalcogenides have emerged as promising materials for visible-light-induced photocatalysis as they are well-known for their narrow band-gap energy. Chalcogenides are compounds consisting of at least one chalcogen anion (S2−, Se2−, or Te2−) and at least one electropositive element [22,23...
