“…Generally, increase of carrier concentration of a semiconductor would affect its Seebeck coefficient, as it is commonly known that the Seebeck coefficient decreases with exponential increase in carrier density. 50 However, such a trend was not found in this experiment where Seebeck coefficient of doped CNTs did not decrease from that of the pristine one ( Fig. 3(b) ), implying that the carrier concentration is varied within the range where Seebeck coefficient exhibits its broad peak value.…”

“…The Seebeck effect, the Peltier effect, and the Thomson effect are the three known thermoelectric effects. The Thomson effect is formed via the combination of the Peltier and Seebeck effects [1][2][3][4]. One of the main advantages of thermoelectric materials is their environmental friendliness, quiet operation, reliability, long-term stability, and absence of moving components.…”

Wearable technologies encompass a diverse range of devices integral to our daily routines. Thermoelectric materials, known for their ability to convert heat differentials into electrical energy, are driving advancements in the automotive, aerospace, consumer electronics, and healthcare sectors. In automotive and aerospace, thermoelectric generators (TEGs) are utilized to enhance fuel efficiency and power onboard systems. In consumer electronics, thermoelectric coolers regulate temperature in devices like laptops and smartphones while also powering wearable technologies and sensors. Healthcare applications include wearable health monitors and drug delivery systems, utilizing thermoelectric devices for thermal management and diagnostics. Smartwatches, intelligent bracelets, sunglasses, and blood pressure sensors exemplify this trend, harnessing the potential of thermoelectric materials to generate power from temperature differentials. Ag2S is a ductile thermoelectric material with a potential use in thermoelectric devices. The aim of the article was to characterize the thermoelectric Ag2S -based material and describe the impact of chosen dopants on material properties. The Seebeck coefficient of pure Ag2S is -1051 μV.K−1, the Seebeck coefficient of Sb-doped material is −2.54 μV.K−1, and that of Ge-doped material is more positive at −87 μV.K−1. Material doped with Ge shows better thermoelectric properties.

Restructured single parabolic band model for quick analysis in thermoelectricity

The single parabolic band (SPB) model has been widely used to preliminarily elucidate inherent transport behaviors of thermoelectric (TE) materials, such as their band structure and electronic thermal conductivity, etc. However, in the SPB calculation, it is necessary to determine some intermediate variables, such as Fermi level or the complex Fermi-Dirac integrals. In this work, we establish a direct carrier-concentration-dependent restructured SPB model, which eliminates Fermi-Dirac integrals and Fermi level calculation and emerges stronger visibility and usability in experiments. We have verified the reliability of such restructured model with 490 groups of experimental data from state-of-the-art TE materials and the relative error is less than 2%. Moreover, carrier effective mass, intrinsic carrier mobility and optimal carrier concentration of these materials are systematically investigated. We believe that our work can provide more convenience and accuracy for thermoelectric data analysis as well as instructive understanding on future optimization design.
