Chemical bath deposition of MoS2 thin film using ammonium tetrathiomolybdate as a single source for molybdenum and sulphur

Recent developments of molybdenum and tungsten sulfides as hydrogen evolution catalysts

“…4 ] with an ammonia solution and using hydrazine hydrate as a reducing agent. 42 However, none of these films were tested for their ability to catalyze HER.…”

Recent status of chemical bath deposited metal chalcogenide and metal oxide thin films

“…This may offer an easy method for the preparation of type-II MoS 2 film of better crystallite. MoS 2 films have been deposited by Roy and Srivastava [141] on a glass/quartz substrate using hydrazine hydrate as a reducing agent. The annealed films show the formation of poorly crystalline 2H-MoS 2 with a preferred orientation along c-axis and about 80% transmission in the visible range.…”

Structural, surface and mechanical characterization of spray-deposited molybdenum disulfide thin films

“…Layered materials such as metal oxychlorides [1], graphite [2], transition metal dichalcogenides (TMDs) [3,4] and quasi ternary systems [5,6] have tribological properties because of their anisotropic nature [7]. MoS 2 , MoSe 2 , WS 2 , and WSe 2 are the most commonly used TMDs in various applications, such as tunnel field effect transistor [8], photovoltaic devices [9], tutelage of industrial surfaces [10] and aviation [11].…”

“…This wide range of applications is due to their adjustable bandgap, high optical absorption and shearing property towards the load. Being non-toxic and cost effective, MoS 2 and WS 2 are preferred over other layered structures [7]. The crystal structure of MoS 2 is mostly hexagonal, in which each layer of molybdenum atoms is sandwiched between two layers of sulfur atoms.…”

“…The layers of molybdenum atoms and sulfur atoms are held together by covalent bond, and the (S-Mo-S) layers are held together by weak van-der-Waals interaction [12]. The triple layer (S-Mo-S) can be arranged in three ways: the hexagonal (2H-MoS 2 ), the rhombohedral (3R-MoS 2 ) and the trigonal (1T-MoS 2 ) [7]. Among these, 2H-MoS 2 stipulates a basal plane parallel to the substrate and hence exhibits low frictional co-efficient [13].…”
