NiTe2 is a layered compound with similar structural characteristics as other transition dichalcogenides (TMDs) family members with the chemical formula of MX2 (M = transition metal, X = chalcogen). Each layer consists of 2D hexagonal arrangement of Ni atoms sandwiched between Te atoms in thermodynamically stable 1T phase. So far NiTe2 crystals have shown rather exotic quantum effects including superconductivity [Zheng2020], topological behavior[Hlevyack2021], and others owing to its rich Fermi surface and colossal density of states at the Fermi level[Xu2018]. Herein, a general chemical vapor deposition (CVD) approach has been designed to prepare two-dimensional metallic NiTe2 thin film. SEM, EDX, and XRD were used for the characterization, which shows that NiTe2 was generated stably with monoclinic phase, and without no hidden NiTe or pure Ni phases. Microreactor was used to understand the intrinsic HER performance of NiTe2. |
