“…The main reason for this improvement can be attributed to the suppression of spurious phases, as visible in the XRD patterns of Figure 10b, including tin(II) oxide (SnO), tin(IV) oxide (SnO 2 ), and tin(II) sulfide (SnS), which were formed due to loss of S. 65 Even though SnS possesses comparable transport properties to CTS, tin oxides, on the other hand, have much poorer transport properties (particularly SnO 2 , with n-type behavior), 66 which detrimentally affects the TEG's performance. In addition, sulfurization also improves the CTS electrical properties by assisting the formation of void-free CTS films, 67 as can be seen by reduced internal resistance from 27.3 to 10.8 kΩ from the slope of I−V curve, which in turn enhances the TEG's performance.…”

In this work, Cu/Zn/Sn-based ternary and quaternary chalcogenides inks were synthesized via hot injection and/or from ball-milled powders. The synthesized inks were used to fabricate thermoelectric generators (TEGs) based on p-type chalcogenide and n-type aluminum-doped zinc oxide (AZO) thin films via spin-coating and magnetron sputtering, respectively. This work highlights the first-ever attempt in a facile and scalable method to fabricate thin-film TEGs using safe, low-cost, and abundant materials. Four different TEGs were fabricated using Cu 2 ZnSnS 4 (CZTS), Cu 2 ZnSnSe 4 (CZTSe), Cu 2.125 Zn 0.875 SnS 3 Se (CZTSSe), and Cu 2 SnS 3 (CTS) chalcogenides. Thermoelectric transport analysis confirmed the respective p-and n-type natures of the chalcogenides and AZO, with their Seebeck coefficients compatible to be coupled in a p−n device. In addition, a full-device analysis has been carried out, and several factors affecting the performance of TEGs were investigated, including the composition, density, and presence of secondary phases in chalcogenide thin films. The maximum power per unit active planar area obtained for CZTS, CZTSe, CZTSSe, and CTS TEGs at a temperature difference (ΔT) of 160 K was ∼43, ∼188, ∼23, and ∼59 nW/cm 2 , respectively, making CZTSe/AZO TEG the champion device.

“…The selected precursor SnCl 2 · 2H 2 O (Sigma-Aldrich purity 99.99%, Darmstadt, Germany) was initially dissolved in water. After dissolution, and with continuous stirring at low temperature, NH 4 OH was added until pH = 8 was obtained and hydrolysis occurred. Then, the temperature was increased up to 100 • C for 2 h. The final product was centrifuged and washed several times until reaching neutral pH and dried at 50 • C for 12 h.…”

“…SnO is a p-type semiconducting oxide which has demonstrated promising applicability as an anode for Li-ion batteries [1], coating for solar energy [2], gas sensing [3], and thermoelectricity [4], among other fields of technological research. However, few works can be found focused on SnO-based applications due to its inherent metastability, as it can be easily oxidized to the most stable SnO 2 .…”

Synergetic Improvement of Stability and Conductivity of Hybrid Composites formed by PEDOT:PSS and SnO Nanoparticles

et al. 2020

View full text Add to dashboard Cite

In this work, layered hybrid composites formed by tin oxide (SnO) nanoparticles synthesized by hydrolysis and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) have been analyzed. Prior to the composite study, both SnO and PEDOT:PSS counterparts were characterized by diverse techniques, such as X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), photoluminescence (PL), atomic force microscopy (AFM), optical absorption and Hall effect measurements. Special attention was given to the study of the stability of the polymer under laser illumination, as well as the analysis of the SnO to SnO2 oxidation assisted by laser irradiation, for which different laser sources and neutral filters were employed. Synergetic effects were observed in the hybrid composite, as the addition of SnO nanoparticles improves the stability and electrical conductivity of the polymer, while the polymeric matrix in which the nanoparticles are embedded hinders formation of SnO2. Finally, the Si passivation behavior of the hybrid composites was studied.

“…On the other hand, tin monoxide, (tin oxide II, stannous oxide) (SnO, Sn 2+ ) romarchite, possesses p-type conductivity and often exhibits a layered structure with tetragonal space group P4/nmn (129) with lattice parameters a = b = 3.803 Å and c = 4.838 Å, corresponding to a litharge structure with a variable optical bandgap, ranging between E G ~2.5–3.4 eV [ 1 , 3 , 7 , 8 ]. In recent years, SnO has generated increasing interest in photocatalysis [ 9 , 10 ] and as a potential thermoelectric material, supported by first principle calculations [ 11 , 12 ] in part due to its low toxicity and abundance compared with other thermoelectric materials. However, its use is still under-explored due to limitations concerning its synthesis in a pristine form without other Sn-based oxides and its easy oxidation to SnO 2 .…”

In Situ Local Oxidation of SnO Induced by Laser Irradiation: A Stability Study

et al. 2021

View full text Add to dashboard Cite

In this work, semiconductor tin oxide (II) (SnO) nanoparticles and plates were synthesized at room conditions via a hydrolysis procedure. X-ray diffraction (XRD) and transmission electron microscopy (TEM) confirmed the high crystallinity of the as-synthesized romarchite SnO nanoparticles with dimensions ranging from 5 to 16 nm. The stability of the initial SnO and the controlled oxidation to SnO2 was studied based on either thermal treatments or controlled laser irradiation using a UV and a red laser in a confocal microscope. Thermal treatments induced the oxidation from SnO to SnO2 without formation of intermediate SnOx, as confirmed by thermodiffraction measurements, while by using UV or red laser irradiation the transition from SnO to SnO2 was controlled, assisted by formation of intermediate Sn3O4, as confirmed by Raman spectroscopy. Photoluminescence and Raman spectroscopy as a function of the laser excitation source, the laser power density, and the irradiation duration were analyzed in order to gain insights in the formation of SnO2 from SnO. Finally, a tailored spatial SnO/SnO2 micropatterning was achieved by controlled laser irradiation with potential applicability in optoelectronics and sensing devices.
