Pulsed Electron Deposition (PED) is a novel technique that can be applied for growing high quality thin films. In this technique, we used an electron beam with a focused diameter of about 1 mm, the energy up to 15 kV, the frequency of 1-10 Hz, the pulse width of 100 ns and the total current of 1.5 kA generated in a discharge system. A remarkable advantage of this technique is the low deviation in composition from bulk to film. By using the PED technique the transparent coducting ZnO and Cu(InGa)Se\(_{2 }\) films were prepared. The effect of some deposition conditions on the properties of film has been examined and discussed. For Cu(InGa)Se\(_{2 }\), the best film was obtained at the discharge voltage of 12 kV and substrate temperature of 400\(^\circ\)C, while for ZnO, the best film was grown at the oxygen pressure of 1.3 Pa and at 400(^\circ\)C.

Abstract:The magnetic properties in CoNiP/Au multisegments nanowire were investigated. All the samples were prepared by electrodeposition method with pH of 5.5 and room temperature. The electrochemical potential of CoNiP was determined by cycle voltammetary. The crystalline structure and morphology of the samples were characterized by X-ray diffraction (XRD), Scanning Electron Miroscopy (SEM) and High-resolution transmission electron microscopy (HRTEM), respectively. The hysteresis loops were measured at room temperature using vibrating sample magnetometry (VSM). The SEM and TEM image showed that the CoNiP/Au nanowires with diameters about 50 nm. The lattice spacing of the CoNiP samples were 0.205 nm. The obtained results of VSM show that, the coercivity is 1006 Oe. The 4-Aminothiophenol (4-ATP) functionalized CoNiP/Au were combined by inverse emulsion method in order to apply to biomedicine. The characteristic Surface Enhanced Raman peak positions of 4-ATP absorbed on the Au segments were occurred without any alterations, which significantly predicted attractive applicability of the colloids for biomedical labeling.
