Cu/In 비에 따른 CuInS2 박막의 특성에 관한 연구
A Study on Properties of Cu/In ratio on the CuInS2 thin film
Abstract
CuInS2 thin films were synthesized by sulpurization of Cu/In Stacked elemental layerdeposited onto glass Substrates by vacuum furance annealing at temperature 200[℃].
And structural and electrical properties were measured in order to certify optimum conditi

Glass/ITO/Cr substrate will be patterned by photolithography.
In AMOLED fabrication, TFT array is on the substrate. Anode electrodes is formed on that TFT. And these are covered with insulator.
PMOLED is formed anode, insulator, cathode separator in order.
This process form electrodes. Organic layer will be deposited on anode.
FMM method is used for small molecules materials

deposition of ink droplets to form a line of drawing or of text. When the paper advances the width of the line, the next pass of the nozzle deposits a slightly different pattern. Thus line by line the complete text or the drawing is formed. After the whole page has been printed, a new sheet of paper is inserted and a new text or a new drawing is created.
In 3D printing, after the first layer has

How about flexible transparent plastic?
Yes, it’s flexible display!!

layer-by-layer growth model. It is noticed that under the bottom of nanorods, ZnO layer with the 608 angle between the nearest neighbors is formed on the side-wall of central axial nanowires, as shown with white arrow in Fig. 1(e) and (f); Meanwhile, the large nanoclusters are found existing on the bottom of nanorods, as shown with black arrows in Fig. 1(f). These observations imply the following
layer (SiON) is deposited on-to the substrate to prevent direct contact with air. The SiON has high resistance for water penetration and good mechanical properties to be used as encapsulation. This material can also be used as anti-reflection layer. The required index of refraction for this layer to act as anti-reflector is 1.9 and SiON has refractive index ranging from 1.8 to 2.0. By applying th
