| چکیده | ||
| در این پژوهش لایه‌های نازک رسانا و شفاف FTO را به روش اسپری بر روی زیرلایه‌های شیشه لایه نشانی کرده‌ایم. تاثیر حجم محلول (ضخامت لایه‌ها) و نسبت آلایش F را بر خواص الکتریکی و اپتیکی لایه‌ها مورد بررسی قرار گرفت. مورفولوژی نانوساختارها و نحوه رشد آنها را توسط تصاویر SEM مورد تجزیه و تحلیل قرار گرفت. طیف عبور اپتیکی توسط دستگاه طیف‌سنج Optics Ocean و مقاومت سطحی لایه‌ها بر حسب حجم محلول (ضخامت لایه) و نسبت آلایش F ، توسط دستگاه چهار میله‌ای مورد بررسی قرار گرفت. بهترین لایه شفاف رسانا از نظر ضخامت که دارای بالاترین ضریب عبور و کمترین مقاومت سطحی است برای اثر ضخامت، نمونه با ضخامت لایه 830 nm با مقاومت ویژه. cm Ω 0.26×10 -3 و ضریب عبور اپتیکی 60 % در محدوده طیف مرئی و از نظر الایش F ، نمونه با آلایش 1.2 HF با مقاومت ویژه 1.19×10-3 (Ω. cm) و عبور %86 بدست آمد. هدف ما از این پژوهش رسیدن به یک حالت بهینه و بر حسب شرایط آزمایشگاهی خود، از رسانندگی و عبور اپتیکی بالا که نتایج بدست آمده در مقایسه با نتایج دیگران قابل توجه می‌باشد. | ||

| چکیده [English] | ||
| In this research, FTO conductive and transparent thin layers were deposited on glass substrates by using spray technique. Effect of solution volume (layers thicknesses) and fluorine doping on layers electrical and optical properties is studied. Their nanostructures morphology and growth mechanism are investigated by SEM images. Optical transmission spectrum is obtained by Optics Ocean spectrometer and surface resistance of layers are measured by Four Probe method .The optimum conductive transparent layer which has maximum transmission coefficient and minimum Resistivity in film Thickness effect for 830 nm Thickness with 0.26×10 -3 Ω.cm surface resistance and 60% optical transmission in visible range and in doping effect for sample with 1.2 HF concentration with 1.19×10 -3 Ω.cm Resistivity and %84 optical transmission have been measured. The obtained results for surface resistance are noticeable with others results. | ||
