Deposition and Characterization of Zinc Oxide Films

Year 2013, Volume: 17 Issue: 3, 49 - 51, 11.07.2014

Abstract

Zinc oxide (ZnO) is suitable for optoelectronic applications due to its electrical and optical properties. The present work deals with the preparation and characterization of ZnO films deposited by the ultrasonic spray pyrolysis method. The starting solution was zinc acetate. Effects of substrate temperature on films properties have been investigated. Optical properties of the films have been characterized by investigating transmittance, absorbance and photoluminescence (PL) spectra. Optical transmission spectrum shows that ZnO films have high transmission (about 80%) in visible region for substrate temperatures at 350oC. Surface morphology of the films has also been analyzed by atomic force microscope (AFM). Four probes conductivity measurements have been used for electrical characterization. The resistivity of ZnO films increases with increasing substrate temperatures

Çinko Oksit Filmlerinin Üretim ve Karakterizasyonu

Year 2013, Volume: 17 Issue: 3, 49 - 51, 11.07.2014

Abstract

Çinko oksit (ZnO) elektriksel ve optik özellikleri sebebiyle optoelektronik uygulamalar için uygun bir malzemedir. Bu çalışma, ultrasonik kimyasal püskürtme tekniği ile çöktürülen ZnO filmlerinin üretim ve karakterizasyonu ile ilgilidir. Filmlerin bazı özellikleri üzerine taban sıcaklığının etkisi araştırılmıştır. Filmler geçirgenlik, soğurma ve fotolüminesans spektrumları ile karakterize edilmiştir. Optik geçirgenlik spektrumu, 350oC taban sıcaklığı için görünür bölgede yüksek geçirgenlik değerlerine (yaklaşık %80 ) sahip olduğunu göstermektedir. Filmlerin yüzey morfolojileri atomik kuvvet mikroskobuyla (AKM) analiz edilmiştir. Elektriksel karakterizasyon için dört uç iletkenlik ölçümleri kullanılmıştır. ZnO filmlerinin özdirenç değerleri artan taban sıcaklığıyla birlikte artış göstermiştir.
