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

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

The optical, electrical and surface differences between as-deposited and annealed CdO films deposited by ultrasonic spray pyrolysis

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 CdOfilms 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 filmswas investigated.
