FE-SEM images of all the samples. For all the samples, the columnar shaped ZnO grains grown normal to the substrate surface are clearly seen. When MZO and GZO films are deposited after ZnO films, it seems that similar columnar shaped grains are formed. It can indicate if the same conditions are preserved, all films can be grownvertically. It is very similar patterns reported in literature [1].
1. Purpose of experiment
포토리소그래피(Photolithography)는 원하는 회로설계를 유리판 위에 금속패턴으로 만들어 놓은 마스크(mask)라는 원판에 빛을 쬐어 생기는 그림자를 웨이퍼 상에 전사시켜 복사하는 기술이며, 반도체의 제조 공정에서 설계된 패턴을 웨이퍼 상에 형성하는 가장 중요한 공정이다. 실험을
Introduction
Problems of YAG
Difficult to control CRI
Wavelength between blue light and yellow light
The samples were ground with an agate mortar, then fired at 1550 ℃ for 10hours.
Result Analysis
Intensity according to fraction of Ce3+ ion : 0.15 > 0.21 > 0.09 > 0.03
Intensity is largest at 0.15. Why?
* Concentration Quenching :
Too much activator concentration
->Reab
Abstract
실험에 사용되는 암세포(A 549)의 medium제조 와 Cell-thawing, Cell-culture의 실험방법에 대해서 알아보았다. 암세포를 배양할 때는 몸 안에 있을 때와 비슷하게 적절한 환경을 만들어 주어야한다. 암세포가 몸 안에서는 면역에 의해 균이 없는 상태에서 죽지 않고 자라지만 체외로 노출된 상태이므로
