Abstract

This is a repository copy of A review on recent developments of thermoelectric materials for room-temperature applications.

Carbon and carbon composites for thermoelectric applications

“…30,85 Among the carbon particles, CNTs and graphene are the most widely used to compose with intrinsically conducting polymers and/or isolating polymers. 24,30,85 3.1 | Conducting polymer-based carbon composites…”

“…To date, the carbon materials focus on CNTs and graphenes, and the organic components of carbon composites are intrinsically conducting polymers that mainly include polyaniline (PANI), poly(3,4‐ethylenedioxythiophene) (PEDOT), and polypyrrole (PPy) as well as some insulating thermoplastics. According to our literature survey, several review articles have been reported to cover organic polymer TE materials filled by carbonaceous fillers and/or inorganic TE nanoparticles such as tellurium, and TE devices 20‐24 . Nevertheless, an overview exclusively highlighting carbon and carbon composites remains absent, motivating us to summarize the recent advances of this topic in the present review.…”

“…According to our literature survey, several review articles have been reported to cover organic polymer TE materials filled by carbonaceous fillers and/or inorganic TE nanoparticles such as tellurium, and TE devices. [20][21][22][23][24] Nevertheless, an overview exclusively highlighting carbon and carbon composites remains absent, motivating us to summarize the recent advances of this topic in the present review. After the introduction, we will individually present CNTs and graphenes as TE materials and the major factors affecting TE performance.…”

Scalable colloidal synthesis of Bi2Te2.7Se0.3 plate-like particles give access to a high-performing n-type thermoelectric material for low temperature application

“…5,6 They are widely used nowadays in commercialized Peltier devices operational in this temperature regime for practical cooling applications and appear promising to power ubiquitous sensors and wearable devices in the future. [7][8][9][10] As n-type narrow band semiconductor, Bi2Te3 crystallizes in tetradymite Bi2Te2Stype structure with rhombohedral symmetry, and exhibits very high ZT values in the lower temperature range of 300-500 K. 11,12 In bulk Bi2Te3, using isoelectronic dopants, Sb at Bisite as (Bi1-xSbx)2Te3 for p-type 13,14 and Se at Te-site as Bi2(Te1-xSex)3 for n-type [15][16][17][18][19][20][21][22] , the most effective substitution was found to be Bi0.5Sb1.5Te3 and Bi2Te2.7Se0.3, exhibiting desirable transport properties and the best ZT. 6 The advent of nanostructuring techniques and the broadly recognized effect of quantum confinement on TE transport properties 23 have stimulated extensive research on nanostructure formation, which has been explored for Bi2Te3 [24][25][26] and its optimal doped compositions [27][28][29][30][31][32] to decouple the inversely correlated electrical and thermal transport.…”

A Facile Chemical Synthesis of PbTe Nanostructures at Room Temperature

“…These materials are environment friendly and mostly used for the development of sustainable energy materials. It has been reported that the narrow band material like PbTe has shown superior thermoelectric (TE) properties and is currently used in different applications [ 2 , 3 ]. These materials have prospective uses in thermal power generation and thermal sensing equipments.…”
