Fabrication of P-N JUNCTION DIODE



BASIC SEMICONDUCTOR
1.1 Semiconductor:-
A semiconductor is a material that has an electrical conductivity between that of a conductor and an insulator. Conductors have very low resistivity (10-2 to 10-8 m) insulator have very high resistivity (>10-2 m), while semiconductors have intermediate values. Semiconductor has resistivity values of order 105 to 100 m.
A semiconductor, such as silicon, has properties somewhere between those of ....etc

INTRODUCTION
Transportation has been instrumental in the global economic growth since the earliest civilisations known to man and efficient traffic management has a major impact on the country s economy. The advent of Information and Communications Technology (ICT) during the Industrial Revolution led to a faster, more productive management of resources worldwide. However, the Industrial Revolution also resulted in huge improvements in road construction and cheaper vehicles. Over the past few years, the exponential ....etc

Josephson Junction


Definition
The 20th century saw many developments in the field of electronics because of basically two reasons

1. The development of transistors, which forms the basics of everything that is electronics.
2. The development of IC, which helped in the fabrication of fast, compact & sophisticated electronic circuits.

In the 21st century we are going to see some radical changes in the approach towards electronics. These are :
1. The replacement of semiconducting devices with superconducting devices.
2. The use of new classic ....etc

ac and dc josephson effect ppt

The Josephson effect is the phenomenon of supercurrent i.e. a current that flows indefinitely long without any voltage applied across a device known as a Josephson junction (JJ), which consists of two superconductors coupled by a weak link. The weak page link can consist of a thin insulating barrier (known as a superconductor insulator superconductor junction, or S-I-S), a short section of non-superconducting metal (S-N-S), or a physical constriction that weakens the superconductivity at the point of contact ....etc

P-N JUNCTION DIODE
OBJECTIVE
1. describe the electrical properties of semiconductors and distinguish between p-type and n-type material;
2. explain the formation of a depletion layer at a p-n junction;
3. discuss the flow of current when the p-n junction diode is forward-biased or reverse-biased;
4. discuss the I-V characteristic of the p-n junction diode.
5. use the diode for half-wave rectification;
6. use the bridge rectifier (4 diodes) for full-wave rectification;
7. represent half-wave and full-wave ....etc
