The Annealing Effects of ZnO Thin Films on Characteristic Parameters of Au/ZnO Schottky Contacts on n-Si

Akkilic, K.; Ocak, Y. S.; Kilicoglu, T.; Toprak, A. (Sumy State Univ, Dept Marketing & Mia, 2012)

200 nm ZnO thin films have been grown on n type Silicon substrates by DC sputtering technique. One of the thin films has been annealed at 300 degrees C for 45 minutes. The Au front contacts on ZnO thin films have been ...
MR images restoration with the use of fuzzy filter having adaptive membership parameters

Guler, I.; Toprak, A.; Demirhan, A.; Karakis, R. (Springer, 2008)

A new fuzzy adaptive median filter is presented for the noise reduction of magnetic resonance images corrupted with heavy impulse (salt and pepper) noise. In this paper, we have proposed a Fuzzy Adaptive Median Filter with ...
