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

SUPERCONDUCTIVITY is the ability of certain materials to conduct electric current with no resistance and extremely low losses. This ability to carry large amounts of currents can be applied to electric power devices such as motors and generators and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the electricity ordinary copper or aluminium wires of same size.Scientists had been intrigued with the concept of superconductivity since its discovery in the early 1900 s, but the extreme low te ....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

Simultaneous Noncontact Measurement of Water Level and Conductivity
water level and conductivity measurement is important in many applications. geophysics, ocean engineering, and the oil industry also rely on this. The gas/oil/water separation can be an example for this. for those application, the method of Noncontact measurement is suitable. For measuring the level, techniques such as Capacitance, radar, ultrasonic, and laser have been used. measurements of level and conductivity simultaneously has no tbeen possible. a novel inductive s ....etc

ABSTRACT

The discovery of superconductivity brings a tremendous change in the field of Science and Engineering from twentieth century onwards. The zero receptivity (or infinite conductivity) of a metal is known as superconductivity and this property of metal can be observed only at very low temperatures. Researchers ar ....etc
