This course aims to establish a solid foundation on the close relationship between crystal structures and materials properties, covering core concepts such as crystal lattice, crystal symmetry (point groups/space groups), crystal stereography, and defects in materials. Furthermore, the concept of reciprocal space is introduced to develop the ability to interpret real-space crystal structures through reciprocal-space diffraction patterns.
(이 강좌는 결정 구조와 소재 물성의 밀접한 연관성에 대한 확고한 기초를 제공하며, 주로 결정 격자, 결정 대칭성 (점군/공간군), 결정 입체 투영법 및 재료 내 결함 등의 핵심 개념을 다룹니다. 또한 역격자 공간 개념을 도입하여, 실공간 결정 구조를 역공간 회절 패턴으로 해석하는 능력을 배양하는 것을 목표로 합니다.)

This STC course is mainly focusing on the freshman and sophomore students who do not have a background about the crystallography.

1. Presentation (10 min)
2. Lecture (55~65 min)
3. Team discussion (0~10 min)

75 min class: lecture (55~65 min), team discussion (0~10 min), presentation (10 min)

Team discussion:
Discussion on team project, team quiz
Take turns to be a team leader who will lead the discussion
Team leader submit the presentation file to TA (Due date: a day before the next class)

Presentation: next class (anyone who will be selected at random to present during the class)
Every team take a turn to give a presentation based on team discussion
Team A -> Team B -> Team C ......
Presentation (10 min): 5 min (share your thoughts) & 5 min (Q&A)

75분 수업은 전 강의에 대한 토의내용발표(10분)와 강의(65분)로 운영됨.

"조별토의":
- 그날 강의에서 배운 내용에 대해, 교수 강의 후에 조별로 토의함.(한 조는 5~6명 정도)
- 조별로 조장이 토의를 주관. (조장은 매번 돌아가며 맡음)
- 각 조의 조장은 토의 요약(PPT)을 제출 (마감: 다음 수업일 전날 자정까지) (*** 모든 조의 조장이 제출해야 함)

"토의내용발표": 다음 수업시간에 발표
- 매 수업 별로 한 조가 (조별토의에서 논의된 내용을 정리하여) 돌아가며 발표함. (예: 첫 발표는 A조 발표, 다음 번에는 B조 -> C조 -> D조 -> A조.......순서로 발표해 감)
- 발표시간: 5분 (+ 5분 질의)
