Thank sir

Is the deby length any different than the diffusin length? Because the depletion region in pn junction and this seems to be the same, but when I looked it up, it says it's not

Please tell me if there are any pre requisites for this course like Solid State Physics or Advanced Electronics because at my institute, I have only taken Electronics 101 in BS, till now. Can you list out topics or lectures required before this to gain most of the theory and derivations?

Hi Christian, Thank you for the wonderful video on MS contacts. I have one question related to the vacuum level. Why is it continuous across the interface? Also, why does it change along with Ec and Ev in equilibrium? thank you for your time!

So nice and educative

You did pretty good explanation. Really helpful (My exam is tomorrow...lol)

bad camera and poor mice

When you draw the exponential decay of holes in the n-type region/donor material at 3:35, that's not the actual/physical distribution of the holes, is it? That is, there aren't more holes at the bottom of the n-type region than there are at the top, right? You're just *plotting/graphing* the concentration of holes in the n-type region as a function of distance from the junction/depletion region, right?

Great video! One question, u mentioned thermionic emission (5:35) is the process of diffusion of electrons from the n type semiconductor to the metal due to the lowering of the potential barrier when a forward bias is applied. How is this different from the diffusion of the minority carriers of a pn junction when a forward bias is applied that lowers the potential barrier? Is the mechanism in pn junctions via thermionic emission too?

Nice

Appreciate!!!

Chutadd awaz ni aari

You forgot the square in the denominator of the ln() function. Anyways this is an amazing video!

Jhonty Rhodes' replica

Thank you for talking about this with a comprehensible accent!!!

What's the symbol row stands for?

pa tak na pohege mara asi dozzi wali

Some of your words are are inaudible, or maybe is it just too hard for me because I am an undergradute physics.

Hey man. U are excellent in teaching. In ur opinion, what is a good book/source to learn about semiconductor device. Tq

You look like thor👀

Can I use this method to predict lifetime in semiconductors?

Your videos are really helpful... could you please make videos of heterojunctions in semiconductor...and quasi Electric fields !!!

Great video's sir. Please can you put them all in a playlist thou.

can u share me calucation of u

Thank you Sir. This made my concepts clear.

This was very insightful. The derivations and steps were very easy to understand. Helped me a lot. Thanks for uploading! Could you also explain 1D and 0D density of states?

Can n1 really be the density of electrons in the traps? If that were the case, n1 would equal Nt*f and Nt = n1+p1 which it doesn't.

U shouldn't be a teacher sir.... u should be a Actor or A Famous model...

excellent videos man

Thank you! Greetings from CSULB

Very helpful -- please keep making videos!

What does it mean by 100% ionization???

why can we assume the work function of a metal is greater than semiconductor? Also, do fermi levels always line up in these junctions?

great explanation thanks a lot

Hi Christian , thanks for the video. Can you explain the working of MOSFET in another video.

Great video but shouldn't the final equation have ni^2?

Couldn't get it. Please explain a bit more. Please tell the name of the book by that UCSD professor.

Hi Christian, excellent explanation. what textbook is your class based on?

great video bro... thanks for the explanation

I really appreciate the effort you put into your videos, but me and a group of colleagues (undergraduates) we are engineering students, not physics and we are doing modelling and simulations on nanoelectronics, so we need to understand quite a bit more about the effects that take place in iii-v semiconductor materials, would really appreciate it if you made a video or two about them

Sir please add lecture on Deep Level Transient Spectrometry and how to calculate Deep level Parameters i e capture Crosssection, emission rate etc. Deep Level Spectrometer works on Principle of S-R-H theory. and i want to contact you on email

thank you so much Christian Wurm! you were so clear. I feel you are the best :)

Hey Christian! Had you in a lot of my former courses and professor Tu just shared your playlist. Gonna be a great resource, thanks for making this!

So cool Christian! Thumbs up

thank you very mach

Thanks for the video! Definitely helped me through my finals.

Awesome. Keep it up

Oh Man, You Are Simply Awesome...Thanks a lot for sharing this wonderful lecture...

I havr no idea what's going on as I am just a senior in high school. I soon wish to understand these concepts!

Would love to do more videos but my research has kept me very busy lately. I'm hoping to get into some MOS stuff for my next videos as I think that has a lot more application. Hopefully next month I can do it. COMSOL would be great for simulating this stuff but for electron based devices I prefer Silvaco.
