Self-formation of thickness tunable Bi₂Te₃ nanoplates on thin films with enhanced thermoelectric performance

Abstract

Bismuth telluride thin films were prepared on flexible substrates by magnetron sputtering and then annealed at different temperatures.

Fiber‐Based Thermoelectric Generators: Materials, Device Structures, Fabrication, Characterization, and Applications

“…Techniques to fabricate FTEG devices by surface modification include drop-casting, [24,60,63,71,77,84,[105][106][107]109,113,147] dip coating, [74,[130][131][132] spin coating, [79][80][81]148] radio-frequency (RF) magnetron sputtering, [20,149,150] thermal vapour deposition, [19,[151][152][153] screen printing, [18,154] and dispenser printing. [128] Drop-casting is one of the most common techniques due to the easy operation without vacuum or high-temperature conditions.…”

Design guidelines for chalcogenide-based flexible thermoelectric materials

“…The common flexible substrates are polyimide (PI), polyether sulfone (PES) 14 , and polyvinylidene fluoride (PVDF) 15,16 ; inorganic nanostructure-based films can maintain flexibility. The common fabrication processes are magnetron sputtering [17][18][19][20][21][22][23] , pulsed laser deposition [24][25][26] , thermal evaporation 27,28 , vacuum-assisted filtration and screen printing 29,30 , etc. Some additional methods like cold pressing and hot pressing 5,31 can maintain the comparable bulk- 6 The electron conductivity is enhanced by Ag, which ejects electrons into the conduction band of the other two composites.…”
