We perform a comprehensive first-principles study of the electronic properties of van der Waals (vdW) trilayers via intercalating a two-dimensional (2D) monolayer (ML = BN, MoSe2, WS2, or WSe2) between a MoS2 bilayer to form various MoS2/ML/MoS2 sandwich trilayers. We find that the BN monolayer is the most effective sheet to decouple the interlayer vdW coupling of the MoS2 bilayer, and the resu...

In this paper, MoS2 and Ni-MoS2 crystal layers were fabricated by the chemical vapor transport method with iodine as the transport agent. Two direct band edge transitions of excitons at 1.9 and 2.1 eV were observed successfully for both MoS2 and Ni-MoS2 samples using temperature-dependent optical reflectance (R) measurement. Hall effect measurements were carried out to analyze the transport beh...

Carbothermic reduction of Molybdenite in the presence of Magnesium oxide was thermodynamically studied. The stability diagrams for MoS2-MgO and MoS2-MgO-C Systems was prepared. The reduction of MoS2 with Carbon in the presence of Magnesium oxide proceeded through the direct oxidation of MoS2 by MgO to form intermediate molybdenum oxidized Species, MoO2 and MgMoO4. The results showed that the g...

Recently, Molybdenum Disulphide (MoS2) promising candidate for low-power digital appli to monolayer (1L) MoS2, few-layer MoS2 (FL-M due to its higher density of states (DOS). Howeve study of FL-MoS2 field-effect-transistor (FET) paper, we report a high-performance FL-MoS2 FE contact resistance (~0.8 kΩ.μm) that is close to t silicon contacts in CMOS technology. A cor performance and the number ...

Density functional theory calculations were performed to investigate the interactions of NH3 molecules with TiO2/MoS2 nanocomposites in order to completely exploit the adsorption properties of these nanocomposites. Given the need to further comprehend the behavior of the NH3 molecules oriented between the TiO2 nanoparticle and MoS2 monolayer, we have geometrically optimized the complex systems ...

Tribological behavior of Cu-MoS2 and Ag-MoS2 nanocomposite lubricant was studied. Cu nanoparticles produced by electrical explosion of copper wires and Ag nanoparticles prepared by electrospark erosion were employed as metal cladding modifiers of MoS2 nanolamellar particles. The tribological tests showed Cu-MoS2 and Ag-MoS2 nanocomposite lubricants changed the friction coefficient of the initia...

As a finite-energy-bandgap alternative to graphene, semiconducting molybdenum disulfide (MoS2) has recently attracted extensive interest for energy and sensor applications. In particular for broad-spectral photodetectors, multilayer MoS2 is more appealing than its monolayer counterpart. However, little is understood regarding the physics underlying the photoresponse of multilayer MoS2. Here, we...

Molybdenum disulfide (MoS2) has recently attracted considerable interests due to its unique properties and potential applications. Chemical vapor deposition (CVD) method is used widely to grow large-area and high-quality MoS2 single crystals. Here, we report our investigation on thermal strain-fractured (SF) single crystalline MoS2, oxidation-fractured MoS2, and normal MoS2 by atomic force micr...
