“…In our continued efforts to evaluate properties of other chalcogenides (apart from WSe x )-WOx combination, tellurium is one of the obvious candidates. Various techniques of Te thin film growth has been employed previously such as electrochemical deposition, sputter coating, vacuum deposition 78 , 79 . In the present study, the Tellurium (Te) film on WO x substrate was prepared by thermal evaporation method due to the fact that the thermal deposition method yields high-quality thin films with a very simple deposition procedure.…”

Tungsten oxide based micro and nanosized structures possess good capacitance as well as enhanced rate capability. Such properties are useful in various applications including electrochemical supercapacitors. Apart from supercapacitance, WO3 and their 2D integrated structures have been modified using different methods to widen their range of the utility. Modification using layer coating, functionalization with other nanomaterial or molecules are methods that can be used to improve the core structure of WO3. But such modifications often alter electrochemical performance. The effects and outcomes of such modifications incorporated in WO3 structures were studied using electrochemical methods, sensing behavior, and morphological examination. One goal for such modifications was to improve robustness of the WO3 structures apart from any change in supercapacitance performance. After detailed electrochemical analyses of WO3 structures, a preliminary study was performed regarding the feasibility of the WO3 based sensors for food safety applications based on electrochemical detection of hazardous dyes in food. Preliminary results obtained after various electrochemical tests including pulsed voltammetry, cyclic voltammetry, and electrochemical impedance spectroscopy suggest the viability of WO3 structures for food safety applications.

“…0.33 eV. 13 Preparation of elemental tellurium from TeO 2 is not as straightforward as the reaction stoichiometry indicates; we reported the complicated nature of the TeO 2 reduction reaction in acidic aqueous solutions. 14 The p-type ZnTe obtained by electrochemical techniques would be more stable than its n-type counterpart for photoelectrochemical applications.…”

Zinc telluride films were prepared electrochemically on gold electrodes via a two-step method. The tellurium͑0͒ was first deposited on the gold electrode by potentiostatically reducing tellurium͑IV͒ dissolved in an acidic solution. The zinc telluride film was then prepared by potentiostatic or potentiodynamic reduction of the tellurium film thus deposited in the presence of zinc sulfate. The film deposition was supported by the frequency decreases recorded during the deposition of tellurium and zinc telluride using an electrochemical quartz crystal microbalance, as well as the spectral changes, accompanying the deposition of these films. The zinc telluride film thus prepared showed a p-type behavior as evidenced by cathodic photocurrents produced upon illumination. The bandgap energy of zinc telluride thus prepared was determined to be about 2.27 eV from its absorption spectrum.

“…Electrodeposition of tellurium has been investigated in both acidic and alkaline media. Qiu et al (1989) electrodeposited Te thin films with a thickness up to 4 µm on monocrystalline tellurium substrate from a TeO 2 -saturated aqueous solution. The thickness was relatively uniform.…”

“…The needle-like surface morphology with random crystal orientation was observed when deposited on (10 1 0) surfaces. At high current densities, polycrystalline films consisting of 1 µm blades with random crystal orientation were produced (Qiu and Shih, 1989). Suggs et al (1991) investigate the electrochemical nucleation and growth of Te on gold (Au) (100) surface in acidic sulfate baths (i.e., 0.4 mM TeO 3 2in X M H 2 SO 4 ).…”

Thermoelectric devices based power generation and cooling systemsystem have lot of advantages over conventional refrigerator and power generators, becausebecause of solid-state devicesdevices, compact size, good scalability, nono-emissions and low maintenance requirement with long operating lifetime. However, the applications of thermoelectric devices have been limited owingowing to their low energy conversion efficiency. It has drawn tremendous attention in the field of thermoelectric materials and devices in the 21st century because of the need of sustainable energy harvesting technology and the ability to develop higher performance thermoelectric materials through nanoscale science and defect engineering. Among various fabrication methods, electrodeposition is one of the most promising synthesis methods to fabricate devices because of its ability to control morphology, composition, crystallinity, and crystal structure of materials through controlling electrodeposition parameters. Additionally, it is an additive manufacturing technique with minimum waste materials that operates at near room temperature. Furthermore, its growth rate is significantly higher (i.e., a few hundred microns per hour) than the vacuum processes, which allows device fabrication in cost effective matter. In this paper, the latest development of various electrodeposited thermoelectric materials (i.e., Te, PbTe, Bi2Te3 and their derivatives, BiSe, BiS, Sb2Te3) in different forms including thin films, nanowires, and nanocomposites were comprehensively reviewed. Additionally, their thermoelectric properties are correlated to the composition, morphology, and crystal structure.
