Finite Quantum Well Part 3

Показать описание

If you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becoming a patron - see the link above :). And a huge thank you to all my existing patrons - you make these videos possible.

In this video, I use the set of equations we derived previously from the boundary conditions and turn this into the graphical method for solving the finite quantum well. I also discuss how this relates to the infinite quantum well model.

This is part of my series on semiconductor physics (often called Electronics 1 at university). This is based on the book Semiconductor Physics and Devices by Donald Neamen, as well as the EECS 170A/174 courses taught at UC Irvine.

Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.

You made me understand quantum wells the right way (and many other things in semi conductor physics and quantum mechanics). I wish you were my professor ! Keep on doing those wonderful physics videos they really are the best of their kind on youtube. In case you didn't really think it through you are giving the chance for people all around the world to understand pretty difficult concepts in physics for free, this is huge man ! A very big thank you from France Jordan :) !

The most descriptive video of this topic!!! Thanks

Very well explained using the graphical method. As it can relates the finite well solution to the infinite well solution visually. Well done.

What’s an explanation. Hats off you sir !!! I wish you were my professor in quantum mechanics ❤️

Thanks for this video which is so helpful to understand the concept..
I feel difficult here 6:48 to understand how you write the expression for E.. Could you please say how did you write that?

how do I find the intercept, I cant figure it out and neither can symbolab

Wow! You're the best... Thank you very much..

ershadtantry

thankyou! But why are we making dimensionless quantity? Isn't it possible to solve without defining it?
