Progress on Two-Dimensional Transitional Metal Dichalcogenides Alloy Materials: Growth, Characterisation, and Optoelectronic Applications

Jia Yu,
Shiru Wu,
Xun Zhao
et al.

Abstract: Two-dimensional (2D) transitional metal dichalcogenides (TMDs) have garnered remarkable attention in electronics, optoelectronics, and hydrogen precipitation catalysis due to their exceptional physicochemical properties. Their utilisation in optoelectronic devices is especially notable for overcoming graphene’s zero-band gap limitation. Moreover, TMDs offer advantages such as direct band gap transitions, high carrier mobility, and efficient switching ratios. Achieving precise adjustments to the electronic prop… Show more

“…Two-dimensional materials, especially transition metal dichalcogenides (TMDs), such as molybdenum disulfide (MoS 2 ) [ 21 , 22 , 23 ], ditelluride (MoTe 2 ) [ 24 , 25 ], tungsten diselenide (WSe 2 ) [ 26 , 27 ], and phosphorene, are considered to be possible replacements for silicon when silicon-based CMOS devices reach their physical limits [ 15 , 16 , 17 , 18 , 19 , 20 ]. These materials, which have high electron mobility, low optical absorption coefficient, and high electrical and thermal conductivities, could enhance the device and circuit performance in many aspects.…”

“…On the other hand, two-dimensional materials are considered promising silicon replacements when silicon-based CMOS devices reach their physical limits [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. A recent focus related to 2D materials are transition metal dichalcogenides (TMDs), such as molybdenum disulfide (MoS 2 ) [ 21 , 22 , 23 ], ditelluride (MoTe 2 ) [ 24 , 25 ], tungsten diselenide (WSe 2 ) [ 26 , 27 ], and phosphorene.…”

“…Moreover, it is necessary to select a photocatalyst that is active in the presence of a specific "sacrificial agent". Therefore, recent research has tended to move from systems containing electron donors to photocatalytic splitting of pure water [12][13][14][15].…”

“…The most frequently studied photocatalysts for water splitting are graphene-based structures [15,[21][22][23] and polymeric graphite-like carbon nitride g-C 3 N 4 [18,19,24]. Unlike photocatalysts based on transition metal sulfides, g-C 3 N 4 is an environmentally friendly material.…”

“…Many methods have been extensively developed for the bandgap engineering strategies, including chemical doping, strain modulation, dielectric screening, alloying, and so on [23][24][25][26][27]. Among which, alloying is particularly highlighted as one of the most effective methods for continuous bandgap modulation [28]. In particular, alloying in diverse TMDCs is available to modulate their bandgaps due to their excellent compatibilities with each other [29,30].…”
