Electronics : Diode (Part 1) – A Solid State Approach, Diode as a Solid State Device-know what is happening inside the diode-Very useful for 2nd year Electronics Engg students.
Course Description
Learn the fundamentals of Diodes and take the first leap to the world of Electronics. This course is on Diode as a Solid State Device. In this course we will thoroughly learn what happens inside a Diode under various applied voltages. So lets have a highlight of the entire course quickly-
- Understand the fundamentals of P-N Junction Semiconductor diode. In this lecture we will understand the Diode from Solid State approach, that is we will learn what actually happens inside the Diode under different circumstances.
- Properties of P-N Junction Semiconductor diode (Concept of Energy Band Diagram, Depletion Width, Electric Field at the junction etc). Examples have also been included to further clarify the concepts.
- Mathematical expressions for Electric potential, Depletion Layer under Equilibrium.
- Discussion on Quasi-Fermi level and Energy Band Diagram plot.
- Carrier concentration as a Function of distance under applied forward bias. Its mathematical expressions have also been derived.
- Current Density as a function of distance under applied forward bias. Its mathematical expressions have also been derived.
- A common misunderstanding- Cut in voltage VS Built in voltage.
- V-I Characteristics of Diode under different bias conditions.
- Understand Diode function Generator & Diode Transfer-function Generator.
- Diode properties under reverse biased condition.
- Discussion on Breakdown phenomena-Avalanche Breakdown & Zener Breakdown.
