Electrodeposition of bismuth telluride thin films containing silica nanoparticles for thermoelectric applications

Temperature dependent Raman and photoresponse studies of Bi2Te3 thin films annealed at different temperatures for improved optoelectronic performance

“…There is gradual enhancement in the hydrophilic nature of the films with annealing temperature. The surface free energies ( γ ) of these as-grown and annealed films were calculated using the relation: 65 with γ w = 71.99 mN m −1 (surface tension of water). The calculated values of γ se are 0.58, 6.47 and 5.99 for as-grown and 473 K and 523 K annealed films.…”

Recent advances of electrodeposition of Bi2Te3and its thermoelectric applications in miniaturized power generation and cooling

“…As shown in Figure 11(a), the early reported ED processes of Bi 2 Te 3 were carried out by the potentiostatic or galvanostatic modes [136][137][138][139][140], which means that the applied potential or current density is fixed from the beginning to the end. However, the continuous deposition is unable to avoid the adverse effect of concentration polarization, thus forming small grain sizes, various orientations (Figure 11d) as well as deviated compositions [131,135,141].…”

Remote Thermoelastic Characterization of Candidate Structural and Protective Coatings for Lead-Bismuth Eutectic Cooled Nuclear Reactors

“…Analysis of the dispersion of optically detected laser generated surface acoustic wave also allows characterization of sub-surface layers [27]. Since also the thermal expansion that goes along with transient thermal gratings can be detected by heterodyne diffraction of impulsive stimulated scattering, the technique also allows determination of the thermal diffusivity of coatings and or substrates [28][29][30][31].…”
