Note that rounding errors may occur, so always check the results. [15] While, historically, lead telluride and silicon-germanium have been used, these materials have suffered from heat conduction through the material.[16]. Page 2. I don't understand!!!! This compound is also known as Tin(IV) Selenide. Bulk SnS2 and SnSe2 are both indirect band gap semiconductors with Eg = 2.18 eV and 1.07 eV, respectively. This idea can be paralleled with the idea of a posture-pedic mattress that does not transfer vibrations laterally. Tin selenide, also known as stannous selenide, is an inorganic compound with the formula Sn Se.Tin(II) selenide is a typical layered metal chalcogenide as it includes a group 16 anion (Se 2−) and an electropositive element (Sn 2+), and is arranged in a layered structure.Tin(II) selenide is a narrow band-gap (IV-VI) semiconductor structurally analogous to black phosphorus.

Search by Systematic name, Synonym, Trade name, Registry number, SMILES or InChI. How did Rizal overcome frustration in his romance? Bletskan 2016 Semiconductor Physics Quantum Electronics and Optoelectronics 19 98. Zhao et al. This boosts the power factor, allowing the material to generate more energy while maintaining good conversion efficiency. K1+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of K–Se bond distances ranging from 3.36–3.97 Å. 20770-09-6. [1], Tin(II) selenide adopts a layered orthorhombic crystal structure at room temperature, which can be derived from a three-dimensional distortion of the NaCl structure. Alias: Stannic Selenide. 3 moles SnSe2 to grams = 829.89 grams. Asked by Wiki User. This phase transition preserves many of the advantageous transport properties of SnSe. SnSe would serve as the p-type semiconductor leg. For chemistry help, visit [12] SnSe nanocrystals have also been synthesized by a gas-phase laser photolysis reaction that used Sn(CH3)4 and Se(CH3)2 as precursors. Structure. Se2Sn. [14] However, in order to take advantage of this ultralow lattice thermal conductivity, the synthesis method must result in macroscale single crystals as p-type polycrystalline SnSe has been shown to have a significantly reduced ZT. Furthermore, the results obtained until the moment indicate that, the structural optical and electrical properties of materials can be influenced by the process conditions and methods used in their deposition.

The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. K(SnSe2)2 crystallizes in the monoclinic Cm space group. Molar mass of SnSe2 = 276.63 g/mol. High‐quality ultrathin single‐crystalline SnSe2flakesare synthesized under atmospheric‐pressure chemical vapor deposition for the first time. So it would be tin(IV) selenide or stannic selenide. 1315-01-1. tin disulfide. I'm very excited to announce our newest paper that has been published in PRL. Even though the record-high efficiency is most likely due to low thermal conductivity of the crystal, the electronic structure may have as important role: SnSe has highly anisotropic valence band structure, which consists of multiple valleys that act as independent channels for very mobile, low effective-mass charge transport within, and heavy-carrier conductivity perpendicular to the layers. Sn4+ is bonded to six equivalent Se2- atoms to form edge-sharing SnSe6 octahedra. 8 moles SnSe2 to grams = 2213.04 grams. Would mean alot! If tin (iv) has a charge of (iv), which is 4, and selenide has a charge of -1, then wouldn't you balance the charges and get SnSe4? The structure is two-dimensional and consists of one SnSe2 sheet oriented in the (0, 0, 1) direction. Component Compounds. View Homework Help - Naming Compounds Worksheet from SNC 2D at Earl Haig Secondary School. 8 moles SnSe2 to grams = 2213.04 grams. See Answer . 5 moles SnSe2 to grams = 1383.15 grams. Structural polytypism in SnS2 and SnSe2 crystals grown by a chemical transport reaction and from a melt was studied by the X-ray diffraction method with a Weissenberg camera. Search by expertise, name or affiliation. The in-plane lattice constants, interlayer distances and binding energies are found to be layer-independent. At room temperature, the crystal structure of SnSe is Pnma. SnS2 or S2Sn. [13], A few-atom-thick SnSe nanowires can be grown inside narrow (~1 nm diameter) single-wall carbon nanotubes by heating the nanotubes with SnSe powder in vacuum at 960 °C. However, at ~750 K, it undergoes a phase transition that results in a higher symmetry Cmcm structure. Any help is MUCH appreciated, you might just save my chemistry grade!
