Finite Quantum Well Part 3

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 :) !

[@shaikmastan1780]

The most descriptive video of this topic!!! Thanks

[@santoshgiri4156]

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

[@azzteke]

You mean: "What an explanation".

[@peterwan9076]

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

[@ayyanarvenkat9304]

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?

[@kungpao_spaghetti5109]

yeah same

[@japhia6037]

it just relate to solution of infinite quantumn well.

[@birdinside28]

Hats off ! You earned a new subscriber!

[@rupam_49]

Thanks sir, very nice explanation.

[@showvik012]

Well explained indeed!

[@ranjitkumarsingh9094]

Very well demonstrated

[@ershadtantry5774]

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

[@twisteddescendants6159]

Thanks

[@user-si1zn3ir7x]

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

[@JordanEdmundsEECS]

You can, but 1. It’s more annoying and 2. This is actually a more general technique used in other fields like electromagnetics, and defining everything to be unitless means when you see this elsewhere you can use the same exact solution.

[@user-si1zn3ir7x]

I get it now thanks!!

[@sagarsaini1991]

amazing

[@camerongrenier5405]

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

Thanks for your interesting video. Your viewers might enjoy this video showing under the right conditions, the quantization of a field is easily produced. The ground state energy is induced via Euler’s contain column analysis. Contain column m must come in to play before over buckling or the effect will not work. The system response in a quantized manor when force is applied in the perpendicular direction. Bonding at the points of highest probabilities and maximum duration( peeks and troughs) of the fields/sheet produced a stable structure out of three fields People say I am just plucked guitar strings. I said you can not make structures with vibrating guitar strings or harmonic oscillators. kzbin.info/www/bejne/raOlpKSfepWpfZYsi=waT8lY2iX-wJdjO3 At this time I’m my research, I have been trying to describe the “U” shape formed. In the model, “U” shape waves are produced as the loading increases and just before the wave-like function shifts to the next higher energy level. Over-lapping all the waves frequencies together using Fournier Transforms, I understand makes a “U” shape or square wave form. Wondering if Feynman Path Integrals for all possible wave functions could be applicable here? If this model has merit, seeing the sawtooth load verse deflection graph produced could give some real insight in what happened during the quantum jumps. The mechanical description and white paper that goes with the video can be found on my KZbin page. You can reproduce my results using a sheet of Mylar* ( the clear plastic found in school folders. Seeing it first hand is worth the effort!
