Fundamentals of semiconductor device physics

Why take this course?

This is an undergraduate course on semiconductor device physics. This course is the first part in a series of two courses on semiconductor device physics.

For any electronics student understanding transport phenomena of charge carriers, drift current, diffusion current, energy band theory of semiconductors, electron hole pairs(EHPs), Junction formation in a diode, extending the device physics to three terminal devices like BJT and MOSFET is necessary.

This course begins with a briefing on the fundamentals that are required to understand semiconductor device physics including some quantum physics fundamentals.

Energy band theory of semiconductors is explained with fermi Dirac distribution function. Intrinsic, extrinsic semiconductors are explained from the purview of energy band theory.

Transport phenomenon talks about mobility, conductivity, Diffusion coefficient and the most important "Einstein's relation" along with continuity equation. These topics are treated quantitatively along with the necessary qualitative analysis.

Based on this knowledge, pn junction diode theory is well explained. It covers contact potential, Maximum field intensity, charge density profile along with the necessary energy band structures in forward bias and reverse bias conditions. The second part of junction diode theory focuses on the quantitative analysis of diode currents, diode capacitive behaviour and diode switching times.

Zener diode, opto electronic devices like photo diode, LED and solar cell are extensively covered.

The main objective of this course is quantitative and qualitative analysis of semiconductors. By the end of this course you will acquaint the theory of electronic devices.

I am editing my review in response to the instructor's response to my original review. Overall, it is a fine course for the undergraduate level. The topics are wide-ranging yet relevant, and presented in a logical fashion. I've been looking but I don't think you'll find a better semiconductor course on Udemy, at least Udemy business, which my company has. But I have several complaints. I do not like some of the analogies that are made between electrons and "growing up" or electrons and society, such as in "125. Lecture 127" and "130. Lecture 3." While cute, they add absolutely nothing to the viewer's physical intuition of how electrons actually behave in a semiconductor. I also don't like how when the instructor makes errors in math or notation, etc., such as in "124. Lecture 26," the editor simply displays a pop-up box showing the viewer what the correct notation or number should be. This happens more than a few times. The more professional way of handling this would be to re-record that part of the episode. Finally, my largest complaint is how the math is done in the examples. Units are dropped entirely until the final answer. When I was an undergraduate studying physics I was told this is a bad habit that should be eliminated. Checking your units is super important and following units through a calculation leads to good physical intuition when you see where certain units come from or cancel. Also it is a good way of checking your math. A course listed as for "undergraduates" should encourage students to show all units at every step when performing calculations.

It's more than I expected. These topics are very very complex but the instructors explanation is logical and understandable
