Comparative study of the electrochemical preparation of Bi2Te3, Sb2Te3, and (BixSb1−x)2Te3 films

Optimizations of Pulsed Plated p and n‐type Bi2Te3‐Based Ternary Compounds by Annealing in Different Ambient Atmospheres

“…[ 19 ] The results indicated good control over the fi lms' compositions, but satisfactory control of the morphology and thermoelectric performance was not reported until later works exhibited Seebeck coeffi cients up to 180 μ V K − 1 after annealing up to 300 ° C for about 1h in argon atmosphere. [ 20 ] Potentiostatic electrodeposition from electrolytes based on nitric acid with tartaric acid added in order to increase the solubility of Sb in the aqueous solutions was reported by Xiao et al [ 21 ] Works by Tittes et al [ 22 ] and in 2008 by Li et al [ 23 ] report the successful deposition of (Bi x Sb 1−x ) 2 Te 3 fi lms , but they lack the thermoelectric characterization of the deposited materials.…”

Optical Properties and Electronic Band Structure of Topological Insulators (on A52B63Compound Based)

“…These compounds possess the rhombohedral crystal structure with five atoms per unit cell belonging to the space groupD 5 3d (R3 m). Sb 2 Te 3 and Bi 2 Te 3 can be used for many different applications such as power generation and cooling devices [10]. Thermoelectric power generators and cooler have many advantages over conventional refrigerators and power generators such as long life, no moving parts, no green house gases, no noise, low maintenance and high reliability [11][12][13].…”

Thermoelectric Characteristics of the Thermopile Sensors with Variations of the Width and the Thickness of the Electrodeposited Bismuth-Telluride and Antimony-Telluride Thin Films

“…2,6,11,12) While various processing techniques such as evaporation, metal-organic chemical vapor deposition, molecular beam epitaxy, and electrodeposition can be used for thermoelectric thin-film fabrication, electrodeposition is attractive because it is a rapid and low-cost method as well as a low-temperature process. 2,5,6,[12][13][14][15][16] While various works were carried out for thermopile sensors of cross-plane configuration, 6,[17][18][19] a thermopile sensor of in-plane configuration has its advantage in fabrication because of easy formation of in-plane thin-film legs by using electrodeposition. In this study, the n-type bismuth telluride (Bi-Te) and the p-type antimony telluride (Sb-Te) thin films were electrodeposited to fabricate thermopile sensors composed of the Bi-Te and the Sb-Te thinfilm legs.…”
