Tailoring CdO Thin Films: Effects of Fe and Ni Dual Doping on Structure and Optical Properties

Abstract

This study used the electrodeposition approach to cover ITO substrates with CdO thin films with pure and Fe–Ni dual-doped in varying volume ratios (1% and 1%, respectively). The structural, optical, and morphological characteristics of pure CdO films covered with Fe and Ni dual doping were examined. XRD measurements were used to analyze the structural characteristics and it was found that Fe and Ni dual-doped CdO films changed the crystal size and damaged the CdO crystal structure. Optical measurements revealed that the use of a different doping element altered the optical band gap. Morphological measurements reveal that the electronegativities and ionic radii of the dopant ions account for the variations in morphological traits.

CdO İnce Filmlerin Özelleştirilmesi: Fe ve Ni Çift Katkısının Yapı ve Optik Özelliklere Etkileri

Abstract

Bu çalışmada, elektrodeposizyon biriktirme yöntemi kullanılarak ITO altlıklara, çeşitli hacim oranlarında (sırasıyla %1 ve %1) saf Fe ve Ni ile çift katkılı CdO ince filmlerle kaplanmıştır. Fe ve Ni çift katkılı saf CdO filmlerin yapısal, optik ve morfolojik özellikleri incelenmiştir. Yapısal özellikleri analiz etmek için XRD ölçümleri kullanılmış ve Fe ve Ni ile çift katkılı CdO filmlerin kristal boyutunu ve CdO kristal yapısını değiştirdiği bulunmuştur. Optik ölçümler, farklı bir katkı elementi kullanıldığında optik bant aralığının değiştiğini ortaya koymuştur. Morfolojik ölçümler, katkı iyonlarının elektronegatiflikleri ve iyonik yarıçaplarının morfolojik özelliklerdeki farklılıkları açıkladığını göstermektedir.
