KCl-MoSe2 X-ray photoelectron spectroscopy (XPS) and Raman spectra display features matching the structural properties of 1T-MoSe2 polyphase, confirming the existence of 1T domains embedded in the 2H-MoSe2 lattice. Moreover, thermogravimetric analysis (TGA) measurements show that the KCl-MoO2 ...
2. The high-resolution TEM and X-ray photoelectron spectroscopy (XPS) were used to confirm that all samples are of high quality with low-defect density and very clean surfaces even after transfer processes (Supplementary Fig. 3). Hence, the influence of defects in different types of samples ...

A dwell time of 0.2 h was used to ensure complete reaction36. XPS characterization of the WSe2 material XPS was used to measure the binding energy of W and Se. Supplementary Fig. S1a, b show the binding energy profiles for W 4f and Se 3d, respectively. The two peaks at 33.19 ...
The proposed mechanism is confirmed by Raman spectroscopy and X-ray photoemission spectroscopy (XPS) for the tellurized MoS2prepared with/without NaOH. The A1gand E12gmodes of the 2H-MoS2phase observed near 402 and 383 cm−1, respectively, in the absence of a Na-scooter, are identical ...
RuO2to distortedh-RuO2that occurs during chemical exfoliation. The phase transition from theh- tot-phase of transition metal dichalcogenides, such as MoS2, MoSe2, WS2, and WSe2, resulting from chemical exfoliation, was reported by Ambrosi and Duerloo22,24. In RuO2NSs, a reverse phase ...
Kawakami2, Glenn G. Jernigan1, Masa Ishigami3, Amy Ng1, Todd H. Brintlinger1, Rhonda M. Stroud1 & Berend T. Jonker1 We report on preparation dependent properties observed in monolayer WS2 samples synthesized via chemical vapor deposition (CVD) on a variety of ...
