Abstract

In this work, CuO films were produced by the successive ionic layer adsorption and reaction (SILAR) method. The oxidation process was applied to CuO films in three different mediums as air, oxygen and argon. CuO films were kept at 400 °C for 2 hours in each medium during the oxidation process. The effect of the selected medium in the oxidation process on the physical properties of the CuO films was investigated. This study showed that the physical properties of the CuO films can vary significantly in different oxidation mediums. XRD studies reveal that all the films are polycrystalline with monoclinic structure and exhibit (-111) and (111) preferential orientations. Grain sizes were determined to vary in the range of 26-28 nm in different oxidation mediums. The XRD results were confirmed by Raman spectrum analysis. The band gap values increased between from 1.80 to 2.11 eV. In addition, it was discovered that with the oxidation of CuO films in argon medium, crystalline melanothallite structure was formed and the surface morphology was significantly changed.

Özet

Bu çalışmada, CuO filmleri ardışık iyonik tabaka adsorpsiyonu ve reaksiyonu (SILAR) yöntemiyle üretilmiştir. CuO filmlerine hava, oksijen ve argon olmak üzere üç farklı ortamda oksidasyon işlemi uygulanmıştır. Oksidasyon işlemi sırasında CuO filmleri her ortamda 400 °C'de 2 saat tutulmuştur. CuO filmlerinin oksidasyon işleminde seçilen ortamın filmlerin fiziksel özellikleri üzerindeki etkisi araştırılmıştır. Bu çalışma, CuO filmlerinin fiziksel özelliklerinin farklı oksidasyon ortamlarında önemli ölçüde değişebileceğini göstermiştir. XRD çalışmaları, tüm filmlerin monoklinik yapıya sahip polikristal olduğunu ve (-111) ve (111) tercihli yönelimler sergilediğini ortaya koymaktadır. Tane boyutlarının farklı oksidasyon ortamlarında 26-28 nm aralığında değiştiği belirlenmiştir. XRD sonuçları Raman spektrum analizi ile doğrulanmıştır. Bant aralığı değerleri 1.80'den 2.11 eV'ye yükselmiştir. Ayrıca CuO filmlerinin argon ortamında oksidasyonu ile kristal melanothallit yapısının oluştuğu ve yüzey morfolojisinin önemli ölçüde değiştiği keşfedilmiştir.
