“…In order to obtain NiO:Li films, the glass substrates covered by NiO films were immersed into lithium hydroxide (LiOH) aqueous solution at room temperature for 20 min following annealed at 550 °C. [52] Sachindranath Das and co-workers used 0.1M nickel nitrate [Ni(NO3)2] in ammonium hydroxide (NH4OH) (pH~9.0) as a cationic precursor and 1% hydrogen peroxide (H2O2) maintained at a temperature of 90 °C-100 °C as an anionic precursor for the deposition of NiO thin films [53]. They investigated the influence of the dipping cycle on the structure, morphology and electrochemical performance of NiO films.…”

“…One such option is the use of metal oxide semiconductors (MOSs). MOS-based sensors are susceptible and can detect even small changes in the environment, such as the detection of harmful and toxic gases [1]. Moreover, they are inexpensive to manufacture, making them an affordable solution for many applications.…”

Nickel oxide (NiO) is one of the p-type semiconductors with unique properties suitable for nanosensor applications. It has a wide range band gap and can be fabricated in various methods, leading to different nanostructures and results. In this study, undoped and lithium (Li)-doped NiO were fabricated using the immersion method to investigate their properties. The field emission scanning electron microscopy analysis revealed that both samples produced two layers of nanosheet and nano coral reef-like (CR) structures. X-ray diffraction patterns confirmed the average crystallite sizes for undoped and Li-doped NiO are 24.70 nm and 31.19 nm, respectively. According to ultraviolet-visible spectroscopy, Li-doped NiO has a higher average transmittance percentage of 53% compared to undoped NiO, which has 40%. The estimated optical band gap values are not much different, with 3.94 eV for undoped and 3.95 eV for Li-doped. Electrical measurements also indicated that Li-doped NiO has a higher conductivity value of 7.9 x 10-2 S.m-1, whereas undoped NiO has 7.71 x 10-2 S.m-1.

“…Lastly, SILAR is generally an inexpensive technique in terms of application necessities. Klochko et al [27] reported the deposition of Li-doped NiO films by the SILAR technique and revealed the effects on the structure's optical, electrical, and thermoelectric characteristics. Kumar et al synthesized SnSe-based quantum dots through the SILAR method for high-performance solar cells [28].…”

In this work, a simple, cost-effective successive ionic layer adsorption and reaction (SILAR) deposition technique has been used to deposit a high-quality tin selenide (SnSe) thin film onto a glass substrate. Structural, morphologic, and thermoelectric properties have been characterized for the prepared thin film. X-ray diffraction (XRD) results of the SnSe thin film reveal an orthorhombic structure phase. The morphological properties of the prepared thin films have been studied using field emission scanning electron microscopy (FESEM). The stoichiometric composition of the deposited thin film and the elemental binding energies of the Sn and Se elements have been investigated with energy-dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). The Fourier transformation infrared (FTIR) spectrum of the SnSe thin film displays vibrational modes of chalcogenides bonds. These results suggest that the developed thin film is crystalline, uniform, and without impurities and is appropriate for energy harvesting applications. The prepared thin film’s Seebeck coefficient and electrical resistivity were estimated through ZEM-3 from room temperature to 600 K. The power factor was evaluated. A substantially high electrical conductivity is observed, which decreases somewhat with temperature, suggesting a semimetal conducting transport—the absolute values of the Seebeck coefficient increase with temperature. The resulting power factor showed the highest values near room temperature and a somewhat decreasing trend as the temperature increased. Despite lower values of the Seebeck coefficient, the substantially enhanced power factor is due to the higher electrical conductivity of the thin film, superior to that reported previously. This precursor study demonstrates promising results for developing high-performance flexible thermoelectric devices via a simple and facile SILAR strategy.
