Columnar Growth of Nanocrystalline ZnO Thin Films Prepared through RF Magnetron Sputtering
نویسنده
چکیده
Nanocrystalline zinc oxide thinfilms have been prepared on glass substrates at different temperatures through planar RF-magnetron sputtering. The particle size reduction with respect to substrate temperature has been studied with x-ray 144 K. Saravanakumar et al diffraction (XRD) and atomic force microscopy (AFM). Cross-sectional transmission electron microscopic (TEM) studies employing dark-field imaging reveals columnar growth of ZnO nano crystals with highly textured growth along [001]. The samples exhibit strong NBE emission at 388 nm followed by a weak and broad visible emission around 420-480 nm.

Microstructure of MmM(5)/Mg multi-layer hydrogen storage films prepared by magnetron sputtering.
Multi-layer hydrogen storage thin films with Mg and MmNi3.5(CoAlMn)1.5 (here Mm denotes La-rich mischmetal) as alternative layers were prepared by direct current magnetron sputtering. Transmission electron microscopy investigation shows that the microstructure of the MmNi3.5(CoAlMn)1.5 and Mg layers are significantly different although their deposition conditions are the same. The MmNi3.5(CoAlM...

متن کاملEffect of Substrate Temperature on the Properties of Nanostructured ZnO Thin Films Elaborated by Sputtering RF-Magnetron
Thin zinc oxide doped with gallium layers were prepared by rf-magnetron sputtering from nanoparticles synthesized by sol-gel method. Increasing the deposition temperature has resulted in a change of preferred orientations of (002) with an intermediate step-like structure of powder. The films showed different morphologies of the surface of the grains that are dependent on the deposition temperat...
