Perovskite BaTiO3 thin films have a wide range of applications for advanced devices. Especially, epitaxial BaTiO3 thin films are highly desirable for these advanced applications. So far, such epitaxial BaTiO3 films have been successfully fabricated on different single-crystal substrates using various deposition techniques including RF magnetron sputtering, molecular beam epitaxy, metallorganic ...

abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
Microstructure of Copper Films Deposited on TiN Substrate by Metallorganic Chemical Vapor Deposition
Thin films of tungsten nitride were deposited from Cl4(CH3CN!W~N Pr) by metallorganic chemical vapor deposition ~MOCVD! in the presence and absence of ammonia (NH3) coreactant. Films were analyzed by X-ray diffraction, Auger electron spectroscopy, and X-ray photoelectron spectroscopy ~XPS!. Films grown with NH3 had increased nitrogen levels and decreased carbon and oxygen levels relative to fil...
Using metallorganic vapor-phase epitaxy, thin films of gallium nitride activated by Eu3+ GaN:Eu3+ have been deposited on sapphire substrates at atmospheric pressure. Luminescence from Eu3+ ions in GaN has been investigated using photoluminescence PL and PL excitation spectroscopy. Experimental results show that Eu3+ ions are excited via energy transfer from the host. Analyses of the observed em...
In this work, CoFe₂O₄@SiO₂@TiO₂ core-shell magnetic nanostructures have been prepared by coating of cobalt ferrite nanoparticles with the double SiO₂/TiO₂ layer using metallorganic precursors. The Transmission Electron Microscopy (TEM), Energy Dispersive X-Ray Analysis (EDX), Vibrational Sample Magnetometer (VSM) measurements and Raman spectroscopy results confirm the presence both of the silic...
Phase-change access memory (PCM) appears to be the strongest candidate for next-generation high-density nonvolatile memory. The fabrication of ultrahigh-density PCM depends heavily on the thin-film growth technique for the phase-changing chalcogenide material. In this study, Ge2Sb2Te5 (GST) and GeSb8Te thin films were deposited by plasma-enhanced atomic layer deposition (ALD) method using Ge [(...
