Electrodeposition of BixSb2−xTey thermoelectric thin films from nitric acid and hydrochloric acid systems

Electrical/Themoelectric characterization of electrodeposited BixSb2-xTe3 thin films

“…Li et al electroplated polycrystalline Bi x Sb 2-x Te 3 thin films on Au substrate in nitric acid and hydrochloric acid systems. [7] The deposited films in nitric acid solution showed higher Seebeck coefficient but rougher morphology than those deposited in hydrochloric acid solution. Frari et al used pulsed electrodeposition techniques to improve the morphology.…”

Electrodeposition of p-Type Sb2Te3 Films and Micro-Pillar Arrays in a Multi-Channel Glass Template

“…However, few Sb 2 Te 3 films prepared by electrochemical deposition have been reported, mainly because SbO + is difficult to dissolve in acidic solution, which leads to poor crystallization of the pure Sb 2 Te 3 and weak TE properties of the final films. Meanwhile, few studies on p-type Sb 2 Te 3 microarrays are available [9,29,36,37,38]. Especially, Sb 2 Te 3 microarrays with high aspect ratio are difficult to obtain.…”

Structural design and manufacture of high packing density micro-thermoelectric power generators using thermoelectric films

“…In our lab [14][15], N-type Bi 2 Te 3-y Se y and P-type Bi 2-x Sb x Te 3 film thermoelectric materials were prepared by electrodeposition. The morphologies of the N-type Bi 2 Te 3-y Se y and P-type Bi 2-x Sb x Te 3 deposits are shown in Fig.8.…”

“…Several kinds of technologies, such as physical vapor deposition, chemical vapor deposition, electrochemical deposition, sputtering and so on, have been used to prepare thermoelectric thin-films [1][2][3][4][5][6][7]. According to the different heat transferring direction, structures of those reported MTEG modules [8][9][10][11][12][13][14][15] can be divided into two categories: vertical structure and parallel structure. For vertical structure, heat transfers along thickness direction of thin-film thermoelectric legs (noted as TE legs).…”
