Semiconductor Electronics/Diode/Introduction

Diode is a marvelous device that passes current only in one direction. Its not necessary that a diode is made of semiconductor, it could be made using vacuum tube valve technology or using electromagnetic switch or using a crystal. We over here concentrate about Semiconductor Diode Alone.

Diode section of Semiconductor Electronics teaches the reader what an Diode is ? How it works ? How it can fail ? It teaches the physics and science behind the operation of the diode.

Diodes can be used for various applications like Voltage Rectification & Regulation, Clipping & Clamping of voltages, making digital logic circuits, modulation, photo-voltaics and so on. Light Emitting Diodes (LED's) are used for light production in visible and invisible region of Electromagnetic spectrum. Many nations have switched their traffic light to LED's so that they have higher operational efficiency. PIN diodes are used for electricity production from light, they constitute much of Solar Cells. Apart from this diodes have many other application which my limited knowledge has failed to take notice.

For a person to be a successful Electronic Engineer, the knowledge, mathematics and science behind a working diode is a must.
