Simulation Study of Optical Transmission Properties of ZnO Thin Film Deposited on Dif-ferent Substrates

Abstract

ZnO is an important II-VI semiconductor material for devices with possible applications such as piezoelectric transducers, gas sensors, transparent electronic in solar cell, saw devices. Based on known research, ZnO is the most promising in optoelectronic and optical applications, especially in UV region. An understanding of the optical properties of ZnO thin film on different substrates is also needed to obtain the optimal configuration for the best performance. In this work, we start our simulation by made a Matlab code to study the Sellmeier equation. The behavior of light transmission of ZnO/BK7 glass and ZnO/Sapphire is studied. Both the variation of thickness of ZnO film and different parameters of Sellmeier model are studied. This approach helps us to determine the best configuration (thin film / substrate) to made advices for optoelectronic applications.

Optical and Structural Study of ZnO Thin Films Deposited by RF Magnetron Sputtering at Different Thicknesses: a Comparison with Single Crystal

“…The variation of optical constant (n) with wavelength (λ) shows a decrease with increasing wavelength (λ) due to decreased absorption of traps and intraband transitions 26 . These results are in conformity with the results 27 .…”

Optical Properties of PS-MgO Thin Films

“…Different concentrations of the thin films have been used as seen in Table 1. The Cauchy-Urbach dispersion model is used to study the refractive index of the thin film as function of the wavelength [11]:…”

Analysis of Reflectance and Transmittance Characteristics of Optical Thin Film for Various Film Materials, Thicknesses and Substrates

“…To perform the functions for which they are designed, thin films must have the proper thickness, composition, roughness, and other characteristics important to the particular application [2,3]. That's why it is important to know the thickness, optical constants, optical and absorption properties as a function of wavelength to predict the photoelectric behavior of modern optoelectronic and optical devices [4]. The structure of a thin film is manifested in the optical properties [5].…”
