ACKNOWLEDGEMENTS I would like to acknowledge the people who have helped to make this work possible. My sincere gratitude is first for my thesis advisor Assist. Prof. O uz BAYRAKTAR for his consistent and thoughtful advice, continuous encouragement and help during the course of this work. I am also grateful to my other advisor Assoc. Prof. Selahattin YILMAZ for his valuable comments and recommendations. I also wish to thank to personnel of IZTECH Centre for Material Research for their help during my material characterization studies. I would like to appreciate deeply to my roommates, Bahar BOZKURT, Gözde GENÇ for their friendships, supports and encouragements. I am grateful to my friends for assisting me with my research and offering advice and discussion. I also present my deepest thanks to Burç YERKES KL because of not only his friendship but also his kind of efforts and endless support. Finally, I would like to express my heartfelt gratitude to my parents, Ne e and Mehmet Ali GÜNE and brother, Batuhan GÜNE for their continuous support and encouragement, which enabled me to overcome difficulties.
