This course will provide the basic knowledge of the oxide thin film deposition and the oxide single crystal growth. In the thin film deposition, the deposition methods through gas phase and the characterization method of the thin film will be explained. In the latter parts, the basic theory of the single crystal growth and various single crystal growth methods will be explained. Moreover, crystal defects will be explained.
At the end of this course, students will be able to:
1) Have the basic understanding of the thin film deposition process through vapor phase.
2) Have the understandings of the thin film deposition by PVD process and CVD process.
3) Have the brief knowledge of the characterization method for the thin film.
4) Have the basic understanding of the bulk crystal growth process through liquid phase.
5) Have the understandings of various bulk crystal growth methods.
6) Have the understanding of crystal defects and their behavior.
