Effect of Sb content on the thermoelectric properties of annealed CoSb 3 thin films deposited via RF co-sputtering

Effect of Fe ion implantation on the thermoelectric properties and electronic structures of CoSb3 thin films

“…32 However, it was found that the optical band gap varied from 0.5 to 0.9 eV. 33 The Raman spectra of P, PA, I 1E15 A, I 2.5E15 A and I 5E15 A thin lms measured at 300 K are shown in Fig. 3.…”

“…However, there is no literature found on the studies of doping of Fe on CoSb 3 by the ion implantation method. Among the thin lm deposition techniques that have been carried out for the deposition of pure phase CoSb 3 are the solvothermal, 31 RF sputtering, 32,33 pulsed laser deposition (PLD) [34][35][36][37] and DC sputtering. 26 Of these techniques, PLD has proven to be one of the well-suited methods for the deposition of CoSb 3 lms with proper stoichiometry.…”

An enhanced power factor via multilayer growth of Ag-doped skutterudite CoSb3 thin films

“…20 Therefore, many studies on the synthesis of high performance thin films, including CoSb 3 films, have been investigated. [21][22][23][24][25][26] For example, A. Ahmed et al 27 obtained a power factor of 7.92 mW m K −2 for the CoSb 2 -containing mixed phase thin film and 1.26 mW m K −2 for the stoichiometric CoSb 3 thin film. However, TE properties of CoSb 3 thin films remain lower than those of bulk materials due to the difficulty of controlling precisely the composition of the thin films.…”

Optimizing the Structural, Electrical and Thermoelectric Properties of Antimony Telluride Thin Films Deposited on Aluminum Nitride-coated Stainless Steel Foil

“…To determine the optimized film deposition parameters, the influences of composition and substrate temperature on crystal quality and orientation, microstructure, and TE properties were investigated using high-resolution scanning electron microscopy (HR-SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). The details of the characterization process are described in our previous publications 14,43 . The Hall measurements were performed on several mm side square samples using an Ecopia HMS-5000 room temperature Hall effect system.…”
