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

What you'll learn:

• Understand the fundamentals of P-N Junction Semiconductor diode by adopting a Solid State approach.
• Analysis of Diode under Forward Bias,its Energy Band Diagram,Carrier Concentration variation w.r.t distance,Electric Field picture
• 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.
• Current Density as a function of distance under applied forward bias.
• 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.
