2019年6月30日 · In the study, we focus on establishing the controllable stoichiometry of SnO x via atomic layer deposition (ALD) and subsequent treatment. The controllable synthesis of SnO 2 and SnO is investigated by multiple analyses involving the …

2022年4月1日 · X-ray diffraction (XRD) established the presence of mixed-phase of Sn, SnO, and SnO 2 components in the nanoparticles. During optical measurements, the redshift of bandgaps was discovered in nanoparticles with SnO 2 content <80% and blue shift in nanoparticles with SnO 2 content >80%.

2016年11月8日 · An extremely sensitive dependence of the electronic properties of SnO x film on sputtering deposition power is discovered experimentally. The carrier transport sharply switches from n-type to...

The high-resolution deconvoluted XPS spectra for Sn3d are shown in Fig. 6(b). Two Sn 4+ peaks with binding energies of 487.11 (Sn3d5/2) and 495.19 eV (Sn3d3/2) are observed.

2024年8月15日 · Heterogeneous Sn/SnO x powders are prepared by the disproportionated reaction of SnO. Plate-like Sn/SnO x is perfectly encapsulated by the N-doped carbon layer. Sn/SnO x @NC microplates possess heterojunction-induced oxygen vacancies. Sn/SnO x @NC-2 electrode delivers excellent electrochemical performance.

Herein, combining device current–voltage (such as ON-state current and field-effect mobility), low-frequency noise (LFN), and gate-bias-stress characteristics, we find that the optimal OPP range is 4.8%–7.2% for the SnOx film deposition at PRF of 70 and 30 W. Based on X-ray photoelectron spectroscopy (XPS), the SnOx films deposited at high power...

2009年3月15日 · The band structure model of SnO x nanolayers obtained by superposition of the XANES and XPS data revealed cross transitions with energy ∼3.7 eV in the presence of the SnO and SnO 2 phases. Surface doping of nanolayers with palladium gave the Pd, PdO, and PdO 2 components, among which PdO was most intense.

2018年11月23日 · Refractive index (n), extinction coefficient (k), effective complex dielectric function (ε) and band gap energy (Eg) of p-type SnO x thin films from 0.75 to 4 eV are studied. 25 nm thick films were deposited by direct current (DC) magnetron sputtering in reactive argon and oxygen atmosphere at different relative oxygen partial pressure (OPP ...

Herein, Ce ions are incorporated into solution-processed SnO x and Ce-doped SnO x ETLs are fabricated for planar PSCs via inkjet printing. The Ce-doped SnO x ETL shows enhanced conductivity and improved energy level alignment with the perovskite layer, which can facilitate charge extraction and transport capabilities.
