Structural modification and band-gap crossover in indium selenide nanosheets

Abstract

Herein, we report on the synthesis of InSe nanosheets.

Synthesis, Characterization and Photo Response Behaviour of InSe and CuInSe2 Nanostructures Using Tris(5‐methyl‐2‐pyridylselenolato)indium(III) as Molecular Precursor

“…The pXRD profiles (Figure ) of these powders displayed a set of reflections originating from (111), (220), (311), (400) planes of cubic phase of InSe (ICDD File No. 00–065‐0100) corroborated by elemental composition analysis by EDX [In:Se atom ratios are 48.2:51.8 (1:1.06), 47.7:52.3 (1:1.09) and 48.6:51.4 (1:1.06) for nanostructures synthesized at 240, 270 and 300 °C, respectively] (Supplementary Information Figure S2). The intensity of these reflections indicates their crystalline nature.…”

Charge Transfer and Functionalization of Monolayer InSe by Physisorption of Small Molecules for Gas Sensing

“…More recently, indium selenide (InSe), a layered material with each InSe layer being composed of a Se–In–In–Se structure, gains increasing attention. − Many studies have been performed to understand its charge carrier dynamics, ,, structure stability, electronic structure, ,− ,, photoluminescence, and surface photovoltaic effect . In addition, the growth , and chemical functionalization of ultrathin InSe nanosheets have been explored, and potential applications based on InSe in nanoelectronics, sensors, optoelectronics, and photodetectors − have been sought.…”

Probing the stoichiometry dependent catalytic activity of nickel selenide counter electrodes in the redox reaction of iodide/triiodide electrolyte in dye sensitized solar cells

“…13,14 This method has been applied to produce a number of high quality nanocrystals including CdSe, CdTe, PbSe, Ag 2 S, Cu 2 S, PbS, Ni 3 S 4 , CdS, ZnS, CuInS 2 Cu 2 ZnSnS 4 and InSe just to mention a few. [15][16][17][18][19] As discussed above, catalytic performance of Ni x Se y depends on the stoichiometric ratio. Similarly, theoretical calculations for I 3 À /I À redox process suggest that the metal sites in a metal chalcogenide are more active compared to the chalcogenides sites.…”
