Abstract

Comparative Study of Structural, Optical and Electrical Properties of SnO&lt;sub&gt;2&lt;/sub&gt; Thin Film Growth via CBD, Drop-Cast and Dip-Coating Methods

Highlights

The development of modern society has become dependent on the progress of science and technology, which is not possible without technological improvement in the field of nano thin films
SnO2 thin films were successfully deposited on a glass substrate via different deposition methods and their effects on structural, optical and electrical properties have been investigated
The XRD patterns of SnO2 thin films deposited by Chemical Bath Deposition (CBD), Drop-Cast and Dip-Coating methods are shown crystalline cubic phase, tetragonal phase and amorphous phase of tin oxide (SnO2) respectively

Summary

Introduction

The development of modern society has become dependent on the progress of science and technology, which is not possible without technological improvement in the field of nano thin films. Inorganic thin films are used in different modern technological sectors such as coating interference filters, anti-reflection (A.R), solar cells, gas sensors, narrow band filters, diodes, biosensors, photoconductors, humidity sensors, IR detectors, temperature control of satellites, magnetic films, waveguide coatings, anticorrosive films, microelectronics devices, etc. SnO2 is one kind of n-type semiconductor that has been familiar to possess several outstanding physical properties such as high transmittance under visible range, high reflectivity for infrared light, high mechanical hardness, low electrical resistivity, wide band gap, excessive conductivity, great chemical stability, thermal stability and good environmental stability [8] [9]. Chemical Bath Deposition method has gained recognition as a significant technique for thin film deposition of absolutely new kinds of oxide films.
