Current-Voltage-Temperature Characteristics of Cd0.73Zn0.27S1-xSex Films Deposited by Spray Pyrolysis

Öz

Cd0,73Zn0,27S1-xSexfilmleri (x=0 ve x=0,8) püskürtme yöntemi ile 275±5°C taban sıcaklığında elde edilmiştir. Bu filmler n-tipi iletkenlik göstermektedir. Filmlerin elektriksel özellikleri altın-yarıiletken-altın düzlemsel yapı formunda incelenmiştir. Bu filmlerin akım-voltaj karakteristikleri ve iletkenlikleri uygulanan voltaj ve sıcaklığa bağlı olarak incelenmiştir. Incelenen filmler ohmik ve space-charge-limited iletim göstermektedir. Filmlerin akım-sıcaklık ölçümleri 257-320K sıcaklık aralığında elde edilmiştir. Cd0,73Zn0,27S0,2Se0,8filminin aktivasyon enerjisi Cd0,73Zn0,27S filminin aktivasyon enerjisinden daha yüksek olduğu bulunmuştur.
