POLYMER LIGHT EMITTING DIODES (PLEDs)

Ø Polymer LED (light-emitting diode) - sometimes called light-emitting polymer or polyLED - is a technology based on the use of polymer as the semiconductor material in LEDs.

Ø Polymers are chemical substances that consist of large molecules that are themselves, made from many smaller and simpler molecules.

Ø Polymers are largely identified with insulation.

Research institutes have come up with ideas to integrate polymers into main stream electronics as it has been establis ....etc

Definition

Polymers are organic materials consisting of long chains of single molecules. Polymers are highly adaptable materials, suitable for myriad applications. Until the 1970s and the work of Nobel laureates Alan J. Heeger, Alan G. MacDiarmid and Hideki Shirakawa, polymers were only considered to be insulators. Heeger et al showed that polymers could be conductive. Electrons were removed, or introduced, into a polymer consisting of alternately single and double bonds between the carbon atoms. As these holes or extra electrons are able to ....etc

The seminar is about polymers that can emit light when a voltage is applied to it. The structure comprises of a thin film of semiconducting polymer sandwiched between two electrodes (cathode and anode).When electrons and holes are injected from the electrodes, the recombination of these charge carriers takes place, which leads to emission of light .The band gap, ie. The energy difference between valence band and conduction band determines the wavelength (colour) of the emitted light.
They are usually made by ink jet printing process. In this m ....etc

1. INTRODUCTION
Imagine a time when your mobile will be your virtual assistant and will need far more than the 8k and 16k memory that it has today, or a world where laptops require gigabytes of memory because of the impact of convergence on the very nature of computing. How much space would your laptop need to carry all that memory capacity? Not much, if Intel's project with Thin Film Electronics ASA (TFE) of Sweden works according to plan. TFE's idea is to use polymer memory modules rather than silicon-based memory modules, and what's more it ....etc
