[8] [9] It has a layer structure similar to that of black phosphorus, featuring 3-coordinate Sn and S centers. [ 5 ] [ 7 ] As for black phosphorus, tin(II) sulfide can be ultrasonically exfoliated in liquids to produce atomically thin semiconducting SnS sheets that have a wider optical band gap (>1.5 eV) compared to the bulk crystal.
Tin (IV) sulfide has various uses in electrochemistry. It can be used in anodes of lithium-ion batteries, where an intercalation process occurs to form Li 2 S. [9] It can also be used in a similar way in electrodes of supercapacitors, which can be used as alternative source of energy storage.

All forms of MoS 2 have a layered structure, in which a plane of molybdenum atoms is sandwiched by planes of sulfide ions. These three strata form a monolayer of MoS 2.Bulk MoS 2 consists of stacked monolayers, which are held together by weak van der Waals interactions.
Tin selenide, also known as stannous selenide, is an inorganic compound with the formula Sn Se.Tin(II) selenide is a narrow band-gap (IV-VI) semiconductor structurally analogous to black phosphorus.
Black, α-SnO adopts the tetragonal PbO layer structure containing four coordinate square pyramidal tin atoms. [11] This form is found in nature as the rare mineral romarchite . [ 12 ] The asymmetry is usually simply ascribed to a sterically active lone pair; however, electron density calculations show that the asymmetry is caused by an ...
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6 , meaning that the 1s, 2s, and 2p subshells are occupied by two, two, and six ...
Molybdenum diselenide (MoSe 2) is an inorganic compound of molybdenum and selenium.Its structure is similar to that of MoS 2. [6] Compounds of this category are known as transition metal dichalcogenides, abbreviated TMDCs.
