In this work, a facile oxidation strategy was developed to prepare novel tungsten disulfide/tungsten trioxide (WS2/WO3) heterostructures for adsorbing organic dyes efficiently by combining the...

2017年11月23日 · The synthesized WS 2 film was characterized by AFM, Raman spectroscopy, PL, and XPS. The optical image of as-synthesized few-layer WS 2 film on a SiO 2 /Si substrate indicates uniform and...

X‐ray photoelectron spectroscopy (XPS) analysis further revealed that the integration of 1D and 2D nanostructures with WS2 has been found effective to alter the interface by the development of ...

2024年11月15日 · Here we achieve phase-switchable preparation of 2D transition metal dichalcogenides using an electrochemical lithium-ion intercalation-based exfoliation strategy by controlling the discharge...

The high-resolution core-level XPS peaks corresponding to W 4+ 4f 7/2 and W 4+ 4f 5/2 were observed at binding energy values of 33.3 and 35.5 eV, respectively, and a small peak at 39.3 eV for W...

2024年7月26日 · Ambient pressure X-ray photoelectron spectroscopy (APXPS) is combined with simultaneous electrical measurements and supported by density functional theory calculations to investigate the sensing mechanism of tungsten disulfide (WS 2)-based gas sensors in an operando dynamic experiment.

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.
