Atomically thin molybdenum disulfide (MoS2) layers have attracted great interest due to their directgap property and potential applications in optoelectronics and energy harvesting. Meanwhile, they are extremely bendable, promising for applications in flexible electronics. However, the synthetic approach to obtain large-area MoS2 atomic thin layers is still lacking. Here we report that wafer-sc...

The present research paper deals with the oxidation process of molybdenum ore. The main target of the present study is the up-gradation of MoO3 from roasted molybdenum ore by a leaching process without waste generation. The most important application of hydrometallurgical processing is the leaching process of the ore and it is the primary process to make pure metal from ore. The present investi...

The ability to grow high-quality, single-crystal transition metal dichalcogenides (TMDCs) is important for the application of electronic and optoelectronic devices. Here, we report epitaxial growth highly-aligned molybdenum disulfide (MoS2) on c-plane sapphire by chemical vapor deposition (CVD). base edge MoS2 flakes mainly along [11−20] crystallographic orientation sapphire. Structural charact...

Monolayer molybdenum trioxide (MoO$_3$) is an emerging two-dimensional (2D) material with high electrical conductivity. Using first-principles calculations and a Boltzmann transport theoretical framework, we predict record low room-temperature phonon thermal conductivity ($\kappa_p$) of 1.57 W/mK 1.26 along the principal in-plane directions MoO$_3$ monolayer. The behavior attributed to combinat...

A simply and facilely synthesized MoO3 solution was developed to fabricate charge injection layers for improving the charge-injection properties in p-type organic field-effect transistors (OFETs). By dissolving MoO3 powder in ammonium (NH3) solvent under air atmosphere, an intermediate ammonium molybdate ((NH4)2MoO4) precursor is made stable, transparent and to be spin-coated to form the MoO3 i...

The formation of the crystalline phases M2, M1, orthorhombic MoO3, and a tetragonal M5O14 (M=Mo,V,Nb) type phase during heat treatment of an amorphous Mo-V-Te-Nb oxide precursor in helium is investigated applying in-situ X-ray diffraction. The precursor was synthesized by precipitation, spray-drying and subsequent calcination of the dried orange powder in air at 275°C. Crystallization of M2 sta...
