Abstract

The cadmium oxide (CdO) films were deposited by ultrasonic spray pyrolysis technique on glass substrates at 300
°C and subsequently annealed at higher temperature up to 500 °C in air ambient. Some physical properties of CdO
films were characterized using different techniques such as optical transmittance, absorbance, four probe method,
and atomic force microscopy. Also, the effect of annealing on the optical, electrical and surface properties of films
was investigated.

Ultrasonik kimyasal püskürtme tekniği ile depolanan ve tavlanan CdO filmleri arasındaki optik, elektrik ve yüzey farklılıkları

Abstract

Kadmiyum oksit (CdO) filmleri taban sıcaklığı 300 °C olan cam tabanlar üzerine ultrasonik kimyasal püskürtme
tekniği kullanılarak elde edilmiştir ve daha sonra 500 °C’deki hava ortamında tavlanmıştır. CdO filmlerinin bazı
fiziksel özellikleri, optik geçirgenlik, soğurma, dört uç metodu ve atomik kuvvet mikroskobu farklı teknikler
kullanılarak belirlenmiştir. Ayrıca filmlerin optik, elektrik ve yüzey özellikleri üzerine tavlama işleminin etkisi
araştırılmıştır.
