Fabrication of Nanowires into Porous Alumina by Electrolysis

This thesis deals with preparation of metal nanowires based on electrodeposition from aqua solution of metallic salts into porous dielectric aluminium oxide templates. The theoretical part covers various bottom-up methods of nanowire preparation using a template, electrochemistry and electrodeposition overview. The Experimental part is focused on the nanowire (Ag, Cu, Ni-H) preparation by means of direct current and alternating current electrodepositon and geometrical characterization of fabricated nanowires by scanning electron and atomic force microscopy. Defects of commercially available and prepared porous alumina templates are mentioned. Branching and coalescence of nanowires are briefly discussed as well
