has more strong light intensity than single chip WLED, but process is too complicate and not cost effective. And electron transfer is slow caused by 2-dimensional chip.
2. RGB-LED Nano Wire ??
Existed RGB-LED structure is 3-chip structure(emit red, green, blue) and mixture structure that constructed with One single chip(emit blue light) and different size quantum dots(emit light by
3. Results and Discussion
3.1 Morphologies and structure(SEM)
Fig. 1 (a)shows SEM image of as-obtained ZnO nanowires of in the first step ranging from 80 to 400 nm in diameters and about 4 mm in length. Gold particles at the tips of the nanowires can be seen in Fig. 1(a). This indicates that the ZnO nanowire growth was governed by a VLSprocess. Fig. 1(a) shows ZnO nanowires obtained under th
VLS가 필요한 고온에서 유리 기판의 손상이나 변형으로 인해 작아야만 했던 active area를 laser ablation 방법을 통해 해결하였다. 이후 RF sputtering 을 이용 TiO2 타겟을 기판과 6cm 거리에 두고 15분 동안 Ar 기체 80mTorr 의 분압 하에서 코팅을 하였다. 이때 기판의 온도는 150도 이다.
