Micro-thermoelectric devices

P- and N-dopable ambipolar bulk heterojunction thermoelectrics based on ladder-type conjugated polymers

“…Micro-thermoelectric devices, with their smaller dimensions than their macroscopic counterparts, can provide a faster response, higher temperature resolution and greater power density. 14 These properties, together with their inherent smaller size, make micro-thermoelectric devices very suitable for wearable devices. While both p- and n-channel legs of large devices can be screen-printed with ease, micro-thermoelectric devices with dimensions of a few tens of microns will face technical difficulties even with inkjet printing.…”

Impact of nanopillars on phonon dispersion and thermal conductivity of silicon membranes

“…Thermoelectrics is a promising technology for green energy harvesting 1,2 Yet, despite the advantages of silicon as a green thermoelectric material, its high thermal conductivity hinders the performance of silicon-based thermoelectric generators. 3 Over the past decade, various methods have been proposed to reduce the thermal conductivity of silicon. [4][5][6][7][8] Among them, methods of surface nano-structuring seem particularly promising as they offer to reduce the thermal conductivity while preserving the high electrical conductivity of the material.…”

Mg3Sb2-based Thermoelectrics: Materials, Interfaces, and Devices

“…Thermoelectric (TE) power generation devices realize the direct conversion between heat and electricity, presenting many indispensable applications in special scenarios 1-3 such as energy supply of space explores 4 , massive sensors for the internet [5][6] , and waste heat recovery from power plants, car exhaust, or fossil fuels [7][8] . In addition, the cooling function of TE devices shows great potential because of the precise and fast micro-zone temperature control [9][10] , especially for the thermal management of microchips [11][12] . Very recently, high-efficiency TE devices assembled with state-of-the-art TE materials are frequently emerged in the prestigious news, such as PbTe 13 , half-Heusler 14 , GeTe 15 , SnSe 16 , Cu 2 Se 17 , AgSbTe 2 2 , Mg 3 Sb 2 9 , and so on.…”
