Title : Coprecipitation Synthesis and Characterization of Nanocomposite AlCr2O4/ MXene (Ti3C2) for Fabrication of Resistive RandomAccess Memory (ReRAM) Device

Abstract:

The spinel, AlCr2O4 is obtained using the sol-gel procedure. Nanocomposite AlCr2O4/MXene was synthesized by the Coprecipitation method. Structural and morphological properties of nanostructures were investigated through different characteristics techniques like XRD, SEM, Raman Spectroscopy, PL, FTIR, UV-Vis Spectroscopy, Electrochemical Impedance Spectroscopy, and EDX. Then multilayer resistive memory device was fabricated by spin coating. The fabricated device was tested by measuring I-V characteristics at different current appliances which encompass all previous results. The bandgap value for nanocomposite reduced to 2.42eV while for AlCr2O4 was measured 3.25eV derived from photoluminescence spectrum. The average particle size of Nanocomposite AlCr2O4/MXene is 25.15nm measured by powder x-ray diffraction. All crystal peaks with R-3c (167) space group, have a standard hexagonal crystal structure. From EDX reading it is proved that the required elements are present in the sample. It is successful electrode material in ReRAM as cleared from Current-Voltage characteristics making them a suitable candidates for useful applications.
