👍👍
👍👍
Ur explanation and teaching style is good don't stop keep going on 👏🏻
U have to explain full ece subjects for our engineering students for gate preparation
Thank you sir very nice gide & very best explain carrier transport phenomena semiconductors teaching video.👍
Hindi me nahi padha skte
It's great 😃
Thank u❤
Thank youu so much ❤
am the first to comment after 3 years🤣
what is the energy requires moving an electron from the bottom of the conduction band to the energy level of electron at rest in vaccum outside the solid A) ionization energy b) electron affinity c) both of them
Thank you so much ❤
Thank you so much ❤
Helpful
This channel is so underrated. Your videos helped me a lot. I think you have followed the text book of Neaman. It would be better if you arrange the playlist according to the chapters. Best wishes for you. Take love ❤
ty sir
thanks alot......this really helps
sir E-EF=-.30 BECAUSE E IS BELOW THE FERMI LEVEL THEN E<EF..????
Sir, I'm so grateful to you. For my semester exams, I just followed your derivations from Chapter 4 and chapter 7 of the Neamen textbook. Thank you so much sir! 😊
How to calculate with calculator density of state 0 to 1eV (my calculator always said math error)
bs handwriting better krlo plis, thank you, your's lovingly, engineering student💀💀💀💀
😂 will try.
Im falling asleep... Because of the way you talk!
He he. Then you are not in the mood for learning. Sleep well!
Pura toh parhaao x=Ce^-kt lik ke chor diya uske bad ka kon par aayega. Answer me ek constant nhi hoga differ eq 2 nd order ka hai
I just discussed the nature of damping in this video. Which is oscillatory and which are non oscillatory. To determine the constants, you need to use the initial or the boundary conditions.
Sir Jo quantum me h numerical Woh kara do
Which topic of quantum?
Where does h variable comes from the taylor expansion. Also there is a missing variable in taylor expansion (x variable)
Read more about Taylor's theorem and expansion.
Quite helpful thank you from pk
Excellent video, very helpful exactly what I was looking for
For the experiment where the diameter of the hole is constant but zou change the small h, so diffrent heights, and measure the amount of water collected in a certain time. How could I possibly word my research question? the small h for me is the distance from the top mark, so where the volume of water is constant to the hole. So I dont measure it from the ground. thank you
superb
Thanku sir ✨❣️
Incredible video. Cleared up so much on this subject!
Fermi energy level depends on dopant concentration, right?
Yes
Sir video ka time decrease kro na....
thanks
Used it in my publication. Great job! Source?
Cheming hu
Could you please show how we can calculate effective mass from band structure? especially when the maximum valence band and minimum conduction band are at k=0?
I love you homie
Wow, nice explanation
Your explanation is more than my teacher in the college .. i even make some mistake when i was written but now I'm right. Thank you sir you are amazing
best explanation!
Nice!!!!
Can you provide the textbook name?
Refer cheming hu or streetman and benerjee
Thanks 😊
Nice video. I have a question. Does the expression for the built-in voltage change for a one-sided pn-junction? Thanks.
No, but you can ignore Xp over Xn as Na is much larger than Nd for p+n junction and the oppositefor n+p. Using Xn*Nd=Xp*Na
Would really appreciate if the the duration was shorter, for the benifit of students
Sir, ur concepts are soo clear. Pls never stop teaching
Pls never stop tecahing
Sir, ur concepts are soo clear. Big fan, sir
good video keep it up!
Nice
