The Effect of Nano Surface Topography on Electrical Properties of Aluminium Films Deposited on Plastic Substrate by Different Technique

Abstract

Aluminium films have been prepared by two different techniques namely direct current (DC) sputtering and thermal evaporation on polyethylene terephthalate (PET) substrates. Effects of techniques types on the structural and electrical characteristics of the films were studied. The effect of nano surface topography on electrical properties of Aluminium films was studied. Sets of experiments were conducted to optimize the deposition of Aluminium films with appropriate deposition parameters. The deposited films were analyzed with atomic force microscopy and four-point probe technique to determine their structural and electrical characteristics. Film characteristics such as electrical resistivity and surface roughness have been determined.
