AFM images of produced ZnO thin film samples in ratio of 5:5(a) and 7:3(b)
Although both surfaces of sample is almost smooth, You can see the more oxygen concentration is contained, the bigger grain sizes of surface is observed.
O2 content of working gas increased,
created bigger grains
transmittance increased
band gap energy increased
refractive index decreased
had more semiconducto
Grain의 크기를 비교해보았다. 그 결과 열처리 후에 전반적으로 밀도가 감소했으며 열처리 온도가 높을수록 경도가 감소하고 Grain size가 커지는 것을 관찰할 수 있었다.

Sintering temperature에 따른 주석(Sn)의 properties의 변화를 분석해보고 주석(Sn)의 properties가 최
grain)를 더 많이 함유하고 있기 때문에 맛이 좋아서 이들을 선호한다고 조사되었다.
2. 시장 분석
2003년~2005년 영국에서 이루어진 조사에 따르면, 시리얼 시장의 규모는 금액과 판매량 면에서 각각 13%와 8% 증가하는 추세이다. 요리하기 편하고, 빨리 먹을 수 있는 시리얼의 특성은 바쁜 현대인에게

폴리싱 작업시 물을 충분히 뿌려야 마찰을 줄여 시편에 생기는 스크래치를 줄일 수 있다
현미경으로 grain의 크기, grain boundary의 형태, 기공의 정도를 관찰한다
grained soil, consolidation settlement of fine grained soil does not occur immediately. Hence, it is common practice to ensure that the consolidation process is expedited and that most of the consolidation takes place during the various phases of construction.

It is very important to note that unlike settlement in sands and other coarse grained soil, consolidation settlement of fine grained soil does not occur immediately. Hence, it is common practice to ensure that the consolidation process is expedited and that most of the consolidation takes place during the various phases of construction.

Do we have whole grain or something other?
What is "whole"?
Is it something in itself or does it have parts?
Oh, spaghetti.
If you have a whole, you have a whole.
Ooh, sausages. You and me is a whole.
If you toddle off, theres a hole in the whole, or if I do.
But a whole cant be broken. It just forms another whole.

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].
