Organic material that has semiconductor properties. Semiconductivity is exhibited by single molecules, short chain (oligomers) and organic polymers. Semiconducting small molecules (aromatic hydrocarbons) include the polycyclic aromatic compounds pentacene, anthracene,and The environment of surface electrons at 'solid-to-liquid' interfaces is somewhat extreme, subjected to intense local electric fields or harsh chemical pressures that high-density ionic charge or polarization of mobile molecules create. In this proceedings, we argue functions of ....etc

A transistor is a semiconductor device used to amplify



A transistor is a semiconductor device used to amplify and switch electronic signals. It is made of a solid piece of semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than the controlling (input) ....etc

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc

rc coupled amplifier circuit using transistor using bc548

Amplifier is a circuit that is used for amplifying a signal. The input signal to an amplifier will be a current or voltage and the output will be an amplified version of the input signal. An amplifier circuit which is purely based on a transistor or transistors is called a transistor amplifier. Transistors amplifiers are commonly used in applications like RF (radio frequency), audio, OFC (optic fibre communication) etc. Anyway the most common application we see in our day to day life is ....etc

Organic Semiconductor and its applications


Why Organic? Advantages

They are also biodegradable (being made from carbon).

This opens the door to many exciting and advanced new applications that would be impossible using copper or silicon.

Why not Organic? Disadvantages

Conductive polymers have high resistance and therefore are not good conductors of electricity.

Because of poor electronic behavior (lower mobility), they have much smaller bandwidths.

Shorter ....etc

Abstract:

Power quality is one of the most talked about topics these days. Both the power utilities and customers are quite concern with the quality of the power supply, whether it be the power generated by the power utilities or the power consumed by the customers respectively. They need these supplies to be at its optimum value so that the cost is efficient; otherwise problems such as over voltage, under voltage, voltage swell, voltage sag, noise and harmonic caused by the disturbances in power supply could be disastrous. Several methods ....etc
