“…[ 6 ] Recently, other kinds of 2D materials such as layered metal dichalcogenides have attracted much research interest due to their excellent electronic and optical properties, as well as nonzero band gap. [7][8][9] Molybdenum disulfi de (MoS 2 ), a typical 2D metal dichalcogenide, exhibits a direct bandgap of 1.8 eV in monolayer and an indirect bandgap of 1.3 eV for bulk or multilayer. [ 10,11 ] It shows a high carrier mobility of ≈200 cm 2 V −1 s −1 for monolayer and ≈500 cm 2 V −1 s −1 for few layers.…”

As an interesting layered material, molybdenum disulfi de (MoS 2 ) has been extensively studied in recent years due to its exciting properties. However, the applications of MoS 2 in optoelectronic devices are impeded by the lack of high-quality p-n junction, low light absorption for mono-/multilayers, and the diffi culty for large-scale monolayer growth. Here, it is demonstrated that MoS 2 fi lms with vertically standing layered structure can be deposited on silicon substrate with a scalable sputtering method, forming the heterojunctiontype photodetectors. Molecular layers of the MoS 2 fi lms are perpendicular to the substrate, offering high-speed paths for the separation and transportation of photo-generated carriers. Owing to the strong light absorption of the relatively thick MoS 2 fi lm and the unique vertically standing layered structure,

“…Graphene as well as MoS 2 exhibits remarkably unique and diverse range of properties, many of which were accounted previously [25][26][27][28]. Although MoS 2 has long been recognized as a lubricant [29,30] in many areas including aerospace industry (weak van der Waals bonds between the sulfur-molybdenum-sulfur leads to low friction properties), the diverse and exotic properties of this particular metal dichalcogenide can be tuned at will by functionalization/hybridization with graphene.…”

Graphene and related inorganic two-dimensional (2D) nanomaterials are an exceptional class of compounds with exotic properties that are technologically intriguing. While graphene itself is chemically inert and a gapless semimetal, its isostructural analog, molybdenum disulfide (MOS 2 ) is chemically versatile with band gaps, thereby finding significant use in a myriad of applications. Although these 2D nanomaterials individually possess tremendous authority for various applications, the combination of these materials in the recent past has created a new paradigm in emerging applications. Here, we summarize the current state-of-the-art and progress over the past three years on the development of hybrids of these layered materials. We highlight their pivotal role in electrochemical energy storage, sensing, hydrogen generation by photochemical water splitting and electronic device applications such as field-effect transistors. Perspectives on the challenges and opportunities for the exploration of these 2D layered hybrid materials are put forward.

“…Both the TMDC materials show higher stability and resistance towards photocorrosion as compared to other organic solar cells 218 . Many of the recent reports have shown that transition metal dichalcogenides and their hybrids can be synthesized in a very cost effective way and have the ability to actively absorb much more radiated energy from the solar energy spectra as compared to the conventional solar cells made from both organic materials as well as silicon [219][220][221] . Furthermore, the relative thickness of the fabricated devices using TMDCs would be much less, bringing in the possibility for transparent, light weight and flexible solar cells.…”

Atomically thin semiconducting transition metal dichalcogenides (TMDCs) layered materials have recently been emerged as an exciting area of research due to accessibility for easy synthesis using various chemical and physical methods. These two-dimensional (2D) layered materials with single layer have direct and wide band gap due to which, they are more suitable for nanoelectronics and optoelectronics device applications. Here, we present a review of the energy related aspects of atomically thin layered materials like MoS 2 , WS 2 , MoSe 2 , WSe 2 , InSe, GaSe, GaTe, MoTe 2 , WTe 2 etc. for supercapacitor, solar cell, lithium ion battery and water splitting application. By significantly assessing various materials and comparing their performances with challenging technology, the advantages and disadvantages of this promising area of energy materials are recognized, which may provide guidelines for future progress.
