英文摘要	Two-dimensional metallic transition metal dichalcogenides are emerging as prototypes for uncovering fundamental physical phenomena, such as superconductivity and charge-density waves, as well as for engineering-related applications. However, the batch production of such envisioned transition metal dichalcogenides remains challenging, which has hindered the aforementioned explorations. Herein, we fabricate thickness-tunable tantalum disulfide flakes and centimetre-sized ultrathin films on an electrode material of gold foil via a facile chemical vapour deposition route. Through temperature-dependent Raman characterization, we observe the transition from nearly commensurate to commensurate charge-density wave phases with our ultrathin tantalum disulfide flakes. We have obtained high hydrogen evolution reaction efficiency with the as-grown tantalum disulfide flakes directly synthesized on gold foils comparable to traditional platinum catalysts. This work could promote further efforts for exploring new efficient catalysts in the large materials family of metallic transition metal dichalcogenides, as well as exploiting their applications towards more versatile applications.; National Natural Science Foundation of China [51290272, 51472008, 51472080, 51432002, 51520105003, 51522212, 51421002, 51672307, 21673054]; Ministry of Science and Technology of China [2016YFA0200103, 2016YFA0200700, 2013CB932603, 2014CB921002]; Open Research Fund Program of the State Key Laboratory of Low Dimensional Quantum Physics [KF201601]; Strategic Priority Research Program of Chinese Academy of Sciences [XDB07030200]; Key Research Program of Frontier Sciences, Chinese Academy of Sciences [QYZDB-SSW-JSC035, QYZDB-SSW-SYS031]; SCI(E); ARTICLE; 8
