NbN thin films are very useful superconducting materials for the electronic devices. Using sputter deposition technique is a cheap alternative to produce of NbN thin films on glass or SiO for the technology applications. The NbN films was coated on glass and SiO/Si substrates by DC magnetron sputtering tehcnique. Pure Nb target was used the production of NbN thin films in different compositions of Argon and nitrogen gases. The effects of different substrate temperatures, sputtering power and, various ratios of Nitrogen/Argon gases were investigated on Superconducting Critical Temperature (Tc). It is seen that increasing the substrate temperature or sputtering power resulted in increased on the Tc. Thereby optimum condition values are deduced by the Residual Resistance Ratio (RRR) calculation and resistance-temperature (R-T) curves. It is observed that the substrate temperature and the flux of nitrogen gas effect (111) preferential orientation during the deposition, whereas the critical temperature of the thin films is affected by the of deposition chamber vacuum. Tc is also highly dependent on the Nitrogen and Argon pressures on sputtering deposited NbN films.

NbN ince
filmler elektronik cihazlar için çok kullanışlı süper iletken malzemelerdir.

Püskürtme
biriktirme tekniğini kullanması teknoloji uygulamaları için cam veya SiO
üzerinde NbN ince filmlerin üretilmesi için ucuz bir alternatiftir.
. Bu
çalışmada, NbN ince filmler, reaktif magnetron püskürtme yöntemi ile cam, Si ve
SiO alt tabakaları üzerine kaplanmıştır. Saf Nb metali, Argon ve azot gazlarının
farklı karşım oranlarında NbN ince filmlerinin üretimi için kullanılmıştır.
Çeşitli
alttaş sıcaklıkları, püskürtme gücü ve Argon / Azot gazı oranının süperiletken
geçiş sıcaklığı (T
c)  üzerine
etkileri araştırılmıştır.
Alttaş
sıcaklığının veya püskürtme gücünün arttırılmasının T
c'yi de arttığı
görülmüştür. Bunun sonunda optimum sıcaklık değerleri, direnç-sıcaklık (R-T)
eğrileri ve Artık Direnç Oranı (RRR) hesaplaması yardımı ile bulunmuştur.
Kaplama sırasındaki alttaş sıcaklığının ve azot gazı akış değerlerinin tercih
edilen yönlendirmeyi güçlü bir şekilde etkilediği gözlenirken, ince filmlerin
kritik sıcaklığı orijinal vakumun kalitesinden etkilenmektedir.
Ayrıca Tc üretilen NbN filmlerinin
kalitesi kaplama işlemi süresindeki Azot ve Argon basınçlarına da oldukça
bağımlıdır.
