Chapter 6. Acknowledgement
I would like to thank a lot of people who help me during my Ph.D. course. At first, I truly want to thank you from the bottom of my heart to my advisor, Prof. Kwanyong Seo. His advice helped me in all the time of research. Also, he gave me encouragement and compliment during my graduate student course.
Also, I would like to thank my thesis committee: Prof. Jin Young Kim, Prof. Tae-Hyuk Kwon, Prof.
Franklin Kim, and Dr. Hana Yoon, for their insightful comments and encouragement. They deserve my most profound appreciation because of their devoted help and support, including professional discussions and collaboration opportunities. Lastly, I wish to express my love and gratitude to my family and Sook Yoon, who have provided significant support. It was truly with their endless love and encouragement that I could come this far. If it had not been for help from everyone, I could not have made outstanding achievements and finished my Master & Ph. D. course in seven years.
감사의 글
처음 The SEO group에 들어오고 싶어서 교수님을 찾아뵈었던 날이 정말 엊그제 같은데 벌써 7 년이라는 시간이 지나 졸업을 하게 되었습니다. 석∙박 통합과정 동안 많이 부족했던 저에게 많은 가르침을 주신 서관용 교수님께 진심으로 감사의 말씀을 드리고 싶습니다. 7 년 동안 교수님께 연구뿐 아니라 여러모로 정말 많은 부분에서 가르침을 받았습니다. 그리고 바쁘신 와중에 저의 박사학위 심사위원으로 참석해 주신 김진영 교수님, 권태혁 교수님, 김종명 교수님, 윤하나 박사님께 깊은 감사의 말씀을 드립니다.
교수님, 박사님께서 많이 도와주신 덕분에 디펜스를 잘 준비할 수 있었습니다.
감사의 글을 쓰면서 제 학위 과정을 돌아보니 정말 고마운 사람들이 많습니다. 지금은 각자의 자리에서 모두 잘 지내고 있는 엄한돈 박사님, 서지훈 박사님, 황인찬 박사님, 제가 학위를 하는 동안 옆에서 많이 도와주셔서 감사합니다. 특히 황인찬 박사님은 때로는 연구실 선배로, 때로는 친구처럼 제 옆에서 많이 도와줘서 고마워요. 그리고 투명 태양전지 연구를 하면서 가장 많은 시간을 같이 보낸 남우형, 정환이에게도 덕분에 연구를 잘 마칠 수 있어서 고맙다는 말을 전하고 싶습니다. 더불어, 친동생처럼 정이 많이 가는 덕재에게도 여러모로 고맙습니다. 또, 보면 볼수록 똑똑하다고 느끼고, 착하고, 같이 연구를 하면서 많은 도움을 받은 원주, 형우도 고맙습니다. 이 외에도 이제 막 연구를 시작한 명현이, 세연이, 유리, 정택이도 고맙고, 앞으로도 지금처럼 열심히 해서 좋은 연구 잘하는 모습 기대할게요. The SEO group 식구들이 있었기 때문에 제가

박사과정을 잘 마무리할 수 있었습니다. 고맙습니다. 앞으로도 계속 같이 공동 연구도 많이 하고 즐겁게 잘 지냈으면 좋겠습니다.
마지막으로, 항상 제 옆에 있어 주고 응원해 준 숙이와 언제나 제 곁에서 든든한 버팀목이 되어주시고 응원과 사랑을 주시는 부모님에게도 진심으로 감사의 말씀을 드립니다.
이외에도 저를 도와주신 많은 분께 감사의 말씀을 드리고 싶습니다. 여러분들이 많이 도와주셨기 때문에 제가 무사히 학위를 마칠 수 있었습니다. 이에 보답하기 위해서라도 더 열심히 살도록 하겠습니다. 감사합니다.
