چکیده
در این تحقیق، یک سیستم چند لایه‌ای نانوساختار رسانای شفاف ZnS/Ag/ZnS/Ag/ZnS بر روی بستر پلی‌اتیلن ترفتالات (PET) با استفاده از نرم‌افزار Essential Macleod طراحی و شبیه‌سازی شد. هدف اصلی از طراحی این ساختار، بهبود و بهینه‌سازی ویژگی‌های تراگسیلی اپتیکی و مقاومت الکتریکی بود. برای دستیابی به این هدف، ضخامت بهینه هر یک از لایه‌ها به گونه‌ای محاسبه شد که همزمان تراگسیلی اپتیکی بالا و مقاومت الکتریکی پایین را ارائه دهد. با استفاده از نرم‌افزار Essential Macleod و تحلیل شبیه‌سازی، ضخامت بهینه برای هر لایه به طور دقیق تعیین شد. این روش طراحی و بهینه‌سازی ساختار ZnS/Ag/ZnS/Ag/ZnS ، امکان استفاده بهینه از این ساختار را در کاربردهای مختلف اپتوالکترونیکی فراهم می‌کند. برخی خواص الکتریکی و اپتیکی سیستم چندلایه‌ای ZnS/Ag/ZnS/Ag/ZnS مورد بررسی قرار گرفت. خواص مورد اندازه‌گیری شامل مقاومت الکتریکی سطحی، تراگسیلی اپتیکی و بازتاب بوده است. ساختار چندلایه‌ای ZnS/Ag/ZnS/Ag/ZnS بهترین نتایج را در صورتی که ضخامت لایه‌های نقره 10 نانومتر و ضخامت لایه‌های ZnS 30 نانومتر بود، به دست آمد. و در این شرایط، ضریب شایستگی 0.0745 بدست آمد که بیشترین مقدار آن است و نشان‌دهنده بهترین کارایی ساختار است. همچنین، مقاومت الکتریکی سطحی پایین در حدود 6.328 و تراگسیلی در ناحیه مرئی برابر با %92.75 بدست آمد. مقاومت الکتریکی پایین و تراگسیلی بالا این ساختار را به عنوان الکترود رسانای شفاف در کاربرد‌های اپتوالکترونیک مقدور می‌سازد.

چکیده English

In this research, a nanostructured multilayer transparent conductive system, ZnS/Ag/ZnS/Ag/ZnS, was designed and simulated on a polyethylene terephthalate (PET) substrate using Essential Macleod software. The primary objective of this design was to enhance and optimize both the optical transmittance and electrical resistance properties. To achieve this, the optimal thickness of each layer was calculated to simultaneously provide high optical transmittance and low electrical resistance. Utilizing Essential Macleod software and simulation analysis, the optimal thickness for each layer was precisely determined. This design and optimization method for the ZnS/Ag/ZnS/Ag/ZnS structure facilitates the efficient use of this structure in various optoelectronic applications. Certain electrical and optical properties of the ZnS/Ag/ZnS/Ag/ZnS multilayer system were investigated. The measured properties included sheet resistance, optical transmittance, and reflectance. The ZnS/Ag/ZnS/Ag/ZnS multilayer structure yielded the best results when the thickness of the silver layers was 10 nm and the thickness of the ZnS layers was 30 nm. Under these conditions, the figure of merit, FTC, was 0.0745 Ω⁻¹, which is the maximum value and indicates the best performance of the structure. Furthermore, a low sheet resistance of approximately 6.328 Ω/sq and a transmittance of 92.75% in the visible region were achieved. The low electrical resistance and high transmittance make this structure suitable as a transparent conductive electrode in optoelectronic applications.
