Molybdenum disulfide for photodetectors FOUR

The bandgap in TMDs can be adjusted by changing the number of layers, which allows tuning of the optical response over a broad range of wavelengths, from the ultraviolet (UV)-visible to NIR. Furthermore, the high carrier mobility and strong interaction of TMDs with light make these 2D materials interesting for optoelectronic applications. Atomically thin layered TMDs, including MoS2, MoSe2, MoTe2 WS2, WSe2/WS2, WSe2, WSe2/h-BN, HfS2, ReS2, ReSe2, SnS2, and WSe2/SnSe2, and the doped MoS2 heterost

Molybdenum disulfide for photodetectors TWO

Comparing the optical absorbance of MoS2, MoSe2, and WS2 monolayers with that of graphene shows that TMD monolayers absorb much more sunlight than graphene. The calculated flux of absorbed photons was 4.6, 3.9, 2.3, and 2.0 mA cm−2 for monolayer MoSe2, MoS2, WS2, and graphene, respectively, compared with 0.3 mA cm−2 for GaAs and 0.1 mA cm−2 for Si in the form of 1 nm thin films. A monolayer TMD can absorb as much sunlight as a 50 nm thick Si film. Wang et al. summarized the bandgaps of different

Molybdenum disulfide for photodetectors THREE

The figure-of-merit for a photodetector is generally evaluated in terms of their photoresponsivity (R), specific detectivity (D*), noise equivalent power (NEP), and the photoresponse time. Photoresponsivity is an electrical response to an incident light illumination, and detectivity is associated with the lowest required optical power intensity for a photodetector to differentiate signal from the actual noise. The intensities of dark and photocurrents generated as a function of applied bias volt

Molybdenum disulfide is the inorganic compound with the formula MoS2

What is Molybdenum disulfide?Molybdenum Disulfide is a moderate water and acid-soluble Molybdenum source for uses compatible with sulfates. Sulfate compounds are salts or sulfuric acid esters formed by replacing one or both hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for water treatment, unlike fluorides and oxides, which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic
