Enhanced thermoelectric properties of InSe through simultaneous increase in electrical conductivity and Seebeck coefficient by Cl doping

Comparison of influence of intercalation and substitution of Cu on electrical and thermoelectric transport properties of InSe alloys

“…13 Lee et al used Cl doping in InSe to increase carrier concentration. 17 In addition, Li et al reported that substituting Se with group VII atoms can induce effective n-type doping in InSe nanosheets. 18…”

High-Conductivity Chalcogenide Glasses in Ag–Ga2Te3–SnTe Systems and Their Suitability as Thermoelectric Materials

“…The TE efficiency is determined by the dimensionless figure of merit ZT = α 2 σ T/ κ, where α, σ, κ, and T denote the Seebeck coefficient, the electrical conductivity, the total thermal conductivity, and the absolute temperature, respectively. − Generally, a larger power factor ( PF = α 2 σ) and a lower κ can achieve a higher ZT . In the recent two decades, various tactics have been implemented to modify the crystalline phases of TE materials to reduce their thermal conductivity while maintaining their high PF , such as nanostructuring, solid-solution alloying, defect engineering, and introducing multiscale defect centers. − A radically different approach may be undertaken depending on the materials with intrinsically low κ, making the PF the parameter to be improved. − …”
