2020年6月24日 · Two-dimensional (2D) metallic transition metal dichalcogenides (MTMDCs) supply a versatile platform for investigating newfangled physical issues and developing potential applications in electronics/spintronics/electrocatalysis. Among these, NiTe 2 (a type-II Dirac semimetal) possesses a Dirac point near its Fermi level.

In this study, we synthesized NiCo2Se4 (NCS) and NiTe2 (NT) nanorod arrays using a hydrothermal method. The confirmation of catalyst formation was achieved through X‐ray diffraction analysis,...

2021年6月1日 · Furthermore, the chemical composition and surface electronic state of NiTe 2 nanosheets were analyzed by X-ray photoelectron spectroscopy (XPS). As shown in Fig. 1 b, two pairs of peaks around 873.5 eV and 855.9 eV are assigned to Ni 2p1/2 and Ni 2p3/2, respectively, manifesting that Ni ions have a +2 valence.

2023年11月1日 · The chemical composition and elemental states of Fe-NiTe/NiTe 2 were measured by X-ray photoelectron spectroscopy (XPS). The XPS survey curves in Fig. S4a show the typical signals of elemental Ni, Fe, Te, O and C.
