Nanowires in Thermoelectric Devices

Abstract

The low efficiency of bulk thermoelectric materials has limited the widespread application of thermoelectric power generation. Theoretical and experimental investigations indicate that materials prepared in the form of nanowires show higher thermoelectric coefficients, thus promising to revolutionize the field. This article reviews the basics of thermoelectric power generation, conventional devices, the role of nanowires and the current status of the field.

Green Biocomposites for Thermoelectric Wearable Applications

“…[13,14] Conversely, TE textiles can also be used as on-the-spot body cooler by the incorporation into sportswear, office chairs or car seats. [12][13][14][15][16][17] Currently, the most performant thermoelectric generators (TEGs) are rigid devices based on toxic and expensive inorganic materials, [5,[18][19][20][21][22][23][24][25][26][27][28][29][30] and, hence, not suitable for wearing and mobile applications. [5,6,31] Consequently, there is a massive interest in fabricating flexible and wearable TE materials based on doped organic semiconductor materials.…”

“…In literature, TE organic p-type textile materials are already reported, using for example the conductive poly (3,4ehtylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), and carbon nanotubes. [15,[32][33][34] On the other hand, reports of n-type organic textiles are rare due to the lack of air-stable ntype organic semiconductor materials. [35] Notable examples are the works of Ito et al, [36] demonstrating the fabrication of doped carbon nanotubes fibers with switchable p-and n-type behavior, and of Ryan et al, [21] reporting the fabrication of n-type yarns by coating commercial poly(ethylene terephthalate) (PET) with a composite of carbon nanotubes and poly(N-vinylpyrrolidone) (PVP).…”

“…Полупроводниковые наноматериалы используются, например, в сенсорах токсичных газов и биосенсорах. Композиционные материалы на основе полупроводниковых нанопроволок и наночастиц могут быть использованы в качестве электродов для литиевых батарей, в солнечных элементах в качестве катализаторов и в других областях техники [1][2][3][4][5].…”

Desorption of Te capping layer from ZnTe (100): Auger spectroscopy, low-energy electron diffraction and scanning tunneling microscopy

“…Principalement, issu de la famille des semi-conducteurs à gap direct avec une largeur de bande interdite de 2,26 eV (549 nm) à 300K et un paramètre de maille a = 6,10132 Å, le ZnTe est considéré comme la structure appropriée pour la réalisation de diodes émettrices de lumière verte, des photodétecteurs UV-verts et des cellules solaires multi-jonctions [4,5,6,7,8,9,10]. Cependant, la réalisation technique de ces dispositifs exige des couches actives de grande qualité cristalline selon le processus d'élaboration qui est généralement la croissance par épitaxie à jets moléculaires (Molecular Beam Epitaxy, MBE).…”
