Tin selenide (SnSe) is a narrow band gap semiconductor comprised of environmentally friendly and earth abundant elements. Such strategy can greatly provide a fundamental and technological support in the development of selenide-based devices and enrich the knowledge of defect chemistry for PEC applications. Tin Selenide is a narrow band gap binary IV-VI semiconductor material. Tin Selenide (SnSe) is a narrow band gap, binary IV–VI semiconductor, suitable for various optoelectronic applications like memory switching devices, photovoltaic, light emitting devices (LED), and holographic recording systems [1-3]. Bulk SnSe has an indirect band gap of 0.90 eV and a direct band gap of 1.30 eV. It is also suitable for various optoelectronic applications like memory switching devices, light emitting devices (LED), holographic recording systems among others. In all cases the Ref. Temperature-dependent transmission experiments were performed for tin selenide (SnSe) thin films deposited by rf magnetron sputtering method in between 10 and 300 K and in the wavelength region of 400–1000 nm. Band gap expansion, shear inversion phase change behaviour and low-voltage induced crystal oscillation in low-dimensional tin selenide crystals† Also, the nanostructured and the morphologies of the thin films were analyzed by scanning electron microscopy. Copper tin sulfide is characterized by a tetragonal-cubic transition at 780°C. Tin selenide is a narrow band-gap (IV-VI) semiconductor and has received considerable interest for applications including low-cost photovoltaics and memory-switching devices. This makes it an attractive 2D material for various photoelectronic applications. Tin selenide finds application in low- cost photovoltaics devices and memory-switching devices.

The structures and band gaps of copper–zinc–tin selenosulfides (CZTSSe) are investigated for a range of anion compositions through experimental analysis and complementary first-principles simulations. With an orthorhombic lattice structure, SnSe displays intriguing anisotropic properties due to the low symmetry of the puckered in-plane lattice structure. Tin Selenide is a narrow band gap binary IV-VI semiconductor material. Tin selenide, also known as stannous selenide, is an inorganic compound with the formula (SnSe), where Tin has a +2 oxidation state. Motivated by the potential applications of tin chalcogenides, investigations of these compounds are becoming particularly active in the field of materials chemistry. Researchers investigated a number of methods to prepare SnSe thin films and powder via brush plating, electro-deposition, spray pyrolysis, hot wall deposition, chemical vapor deposition, vacuum evaporation, chemical bath deposition, atomic layer deposition, laser ablation and D.C. Magnetron sputtering. It has multinary-metal chalcogenide compositions containing only non-toxic and abundant elements, and hence it is widely used in developing environmentally sustainable processes and … Recent Attended Shows: IMAT Virtual Edition October 26 - 28 TMS 2020 Feb 23 - 27 San Diego CA Booth 700 AABC Europe Jan 12 - 16 Wiesbaden Germany of Material Science and Engineering, Nanjing Institute of Technology, China Direct energy gap: 0.8 eV Debye temperature: 215 K Gruneisen parameter: 2.98. * It is also suitable for various optoelectronic applications like memory switching devices, light emitting means it is good for absorption of the rays. XX is the XXth reference in the list of references. State Key Laboratory of Chem/Bio-Sensing and Chemometrics, College of Chemistry and Chemical Engineering, Hunan University, Changsha, P. R. China The good agreement in band gap between GGA-PBE and experiment to some extent is due to the PAW potentials which capture the six valence electrons of Se (4s24p4) and the four of Sn (5s25p2) properly. It is often alloyed with lead to make lead tin telluride, which is used as an infrared detector material.. Tin telluride normally forms p-type semiconductor (Extrinsic semiconductor) due to tin vacancies and is a low temperature superconductor. TABLE 2. Tin(II) selenide is a narrow band-gap (IV-VI) semiconductor and has received considerable interest for applications including low-cost photovoltaics and memory-switching devices. FTIR was used to calculate bandgap information comparison with undoped PbSe. Fetching data from CrossRef. Influence of the substrate temperature on the structural, optical, and electrical properties of tin selenide thin films deposited by thermal evaporation method N. Kumar Department of Physics and Electronics, Dr. Ambedkar Road, University of Jammu, Jammu‐180 006, Jammu and Kashmir State, India Fig. The band gap of SnSe 2 can be tuned from bulk to few-layer thin films with a wide electromagnetic spectrum range (from 1–2 eV). Selenide with a narrow band gap can be used as a promising photoelectrode in photoelectrochemical (PEC) water splitting. 29 In addition to exploring any changes in local crystal structure we also wished to explore how this material would interact with the encapsulating tubules in terms of the composite physical properties. or in a thesis or dissertation provided that the correct acknowledgement is given We benefited from Rutherford Backscattering Spectrometry with 2 MeV 4He ions to determine the depth profile of the elements in tin selenide. Safety Information. The repaired SnSe film under an optimal selenization time shows a remarkable increase in both the limiting photocurrent density and environmental stability by over 3 times in comparison with the pristine film. Tin selenide (SnSe) as a common binary selenide is easy to investigate and possesses the universality of metal selenides like narrow band gap and the issue of oxidation. is available on our Permission Requests page. low cost, absence of toxicity, and good abundance in nature, it is becoming a candidate for future multifunctional devices particularly for light conversion applications. the whole article in a third party publication with the exception of reproduction
