주요 응용
As a result of its direct band-gap, single-layer MoS2?has received much interest for applications in electronic and optoelectronic devices (such as transistors, photodetectors, photovoltaics and light-emitting diodes). It is also being explored for applications in photonics, and can be combined with other TMDCs to create advanced heterostructured devices.
개요
Few-layer molybdenum disulfide (MoS2) is considered to be one of the most attractive?materials?for next-generation nanoelectronics. This is due to its silicon-level charge mobility and high current on/off ratio in thin-film transistors. Compared to monolayer? MoS2 (which needs?a deposition of an additional high-k?dielectric layer such as HfO2), few-layer?MoS2 can be operated on its own. This makes it more appealing for fabricating transistors and other optoelectronic devices.제조 방법
Synthetic?- Chemical Vapour Transport (CVT)화학적 성질
dark grey or black powder,Molybdenum disulfide, MoS2, the most common natural form of molybdenum, is extracted from the ore and then purified for direct use in lubrication. Since molybdenum disulfide is of geothermal origin, it has the durability to withstand heat and pressure. This is particularly so if small amounts of sulfur are available to react with iron and provide a sulfide layer which is compatible with MoS2 in maintaining the lubricating film.용도
Molybdenum disulfide (MoS2) is one of the most widely used lubricants in space systems.it is a common additive that improves the antiseize properties of wheel bearing grease.Molybdenum disulfide (MoS2) has been used for many years as a solid lubricant because of its interesting friction-reducing properties related to its crystalline structure. MoS2 is a lamellar compound made of a stacking of S-Mo-S layers . In each of them, the molybdenum atom is surrounded by six sulfur atoms located at the top of a trigonal prism. The distance between a molybdenum atom and a sulfur atom is equal to 0.241 nm, whereas the distance between two sulfur atoms from two adjacent layers is equal to 0.349 nm. This characteristic was often used to explain easy cleavage between the layers and therefore the lubricating properties of MoS2.정의
Natural molybdenum sul-fide found in igneous rocks and metallic veins.일반 설명
Molybdenum disulfide is a two dimensional layered material. Monolayers of transition metal dichalcogenides (TMDs)exhibit photoconductivity. The layers of the TMD can be mechanically or chemicaly exfoliated to form nanosheets.위험도
