Now the viewpoint emerging in visualizing the conducting polymers as a material of principal MICROELECTRONICS. advancement research towards Polytronics. We making hope that, in the forthcoming years semiconductor chips.

They are of low cost and printed, creating a so called top gate can be mass produced as the battery transistor. material is roughly 0.5 millimeters dielectric layer polyvinylphenol.Finally How the gate thick. semiconductor polymer dries is very crucial. The molecular chains must line up in a way that makes it easy for an electron to hop from one chain to another, but the polymers tend to form into disordered microstructure that reduces electron charge. 4 interference in electronic devices. Construction: The new battery consists of 3 different layers. It has conventional zinc manganese dioxide components as anode and cathode which are thin foil-like plastic sheets. Electrolyte is a polymer gel placed between electrodes. . There are two types of OLEDs: Uses: .
