Electronics : Diode (Part 1) - A Solid State Approach

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.
