Effect of Sb doping on the structural, electrical, and optical properties of SnO2 thin films prepared through spray pyrolysis

Highly sensitive thermoelectric touch sensor based on p-type SnO x thin film

“…A metallic behavior is observed for the thicker film, with ρ=12×10 −7 Ω m, typical of metallic Sn (1.1×10 −7 Ω m at room temperature [32]). The measured electrical conductivity values for thinner SnO x films are higher when compared to the values previously published for the tin oxide materials (SnO and SnO 2 ) [6,16,30,33]. The mobility of charge carriers (and the electrical conductivity) depends on the morphology of the structures.…”

“…Moreover, a n-type SnO x is revealed by the thicker sample of 160 nm (S=−7.7±0.3 μV K −1 ), which could be attributed to the presence of metallic Sn atoms in the structure, as revealed by XRD data (see figure 1). Typically, bulk SnO samples exhibit higher S coefficient values (S>300 μV K −1 [16]) than the thin film, with low σ [16], and considering display applications, thin film SnO x is more appropriate. Using the Van der Pauw configuration we measure the σ of 4.1×10 2 ±0.9 S m −1 and 6.9×10 2 ±0.5 S m −1 for the 60 nm-SnO x and 90 nm SnO x films, which results in a PF value of 29.7±1.1 μW m −1 K −2 and 8.7±0.2 μW m −1 K −2 , respectively.…”

“…In this way, tin oxide films (SnO x ) seems to be an ideal candidate for display technologies. They show lower band gap (2.5-3 eV) than ZnO films (3.2-3.5 eV), are earth abundant, facile synthesis (melting point of Sn of 505 K), and ecofriendly material [15,16]. Furthermore, they exhibit low electrical resistivity, high Seebeck coefficient and high optical transmittance [16,17], which make them useful for a TE touch device.…”

Temperature-dependent structural and optical properties of Sb-doped SnO2 nanoparticles and their electrochemical analysis for supercapacitor application

“…Tin oxide (SnO 2 ) is a fascinating metal oxide semiconductor because it has the highest carrier mobility among the oxide materials and a relatively large band gap (3.6 eV). 2 Also, its inherent wide band gap causes its absorption edge to lie outside the visible spectral region. SnO 2 is highly resistant to strong acids and bases and exhibits excellent stability over a wide temperature range.…”

Controllable synthesis of TiO 2 /ATO conductive composite: effects of TiO 2 surface properties

“…Moreover, the little content of ZrO 2 is rarely detected. In addition, the absence of any other Sb phase peaks in the composites implies that the Sb might be incorporated into the crystal lattice of SnO 2 [14][15][16].…”
