Great video! I just have one question: why the vacuum band needs to bend too? Shouldn't it stay constant through the interface?

Hello. Thanks for the video. I still have a dought. In dr=r^.dr, which dr is the vector? Isn't it the right one (and not the left one)?

Perfect explanation, it really help me to undestand.

i think it is important to distinguish between the unbuffered "UB" anb buffered logic families. very important when using logic as oscillators or other analog applications.

you are my Hero, i just saw the whole 6 chapters, and figured out i was lost regarding the two levels system, while only needing to understand the Fermis Golden Rule THANK U

This doesn't quite jive if you compare the integral of the probability distribution function psi(psi squared) outside the barrier, outside the well, to known approximations of the tunnelling probability using only factor G, barrier energy, energy and Length of the well and barrier

Thank you

Thank you

Thank you

Thank you

Thanks sir!

grrrr8

Best video about dealing with the Schrodinger time-dependent equation !! Thank you so much, you're making studying for my finals way easier and refinding the motivation for theoretical chemistry again !! :)

This seems like a really dumb video, Where’s the phase info? At the very least, why isn’ there any complex xfer jwt (s) expression

Hey, love the video! I couldn’t help but notice the shape of the fermi function looks a lot like windowing functions used in discrete and continuous signal processing. In those cases, attenuation of the amplitude as you get further from the 0 point on the x axis is expressed in dB. I was wondering if there’s anything similar for the fermi function

Great explanation. Was a very good refresher for me!

hi, just wanna know does it make sense to ask the optical path for a electron wave?

Great video!! ^^

Thank you so much Sir.

Each electron has its own momentom. So what happens if the electron that you marked has 0.2eV gets the 2eV of the photon (which gives total of 2.2 and does not suit the gap)? It also cannot jump? I thought that in the case of additional energy the electron jumps and the rest of the energy becomes heat.

if VSB is more negative than 2phiF then Vth becomes imaginary, explain? If we apply Modulus then for sweeping VSB across negative range we still get VSB + 2phif as an Increasing function due to modulus,same as VSB in positive range. Ran into this problem while solving Razavi Cmos Analog design problems

For those That prefer a mechanical analog you can look at harmonics of a guitar string and such. The video I present is another mechanical method of quantizing a system. It is one of two methods where structures can actually be produced. ruclips.net/video/wrBsqiE0vG4/видео.htmlsi=waT8lY2iX-wJdjO3 Area under a curve is often equivalent to energy. Buckling of an otherwise flat field shows a very rapid growth of this area. If my model applies, it may show how the universe’s energy naturally developed from the inherent behavior of fields. Under the right conditions, the quantization of a field is easily produced. The ground state energy is induced via Euler’s contain column analysis. Containing the column must come in to play before over buckling, or the effect will not work. The sheet of elastic material “system” response in a quantized manor when force is applied in the perpendicular direction. Bonding at the points of highest probabilities and maximum duration( ie peeks and troughs) of the fields “sheet” produced a stable structure when the undulations are bonded to a flat sheet that is placed above and below the core material.

Rma😂

Audible sound is no different than any other radiation, it's all induction

Please make a follow up of this video. Great explanation!!

Thank you very much

Thanks for your videos! Your drawings + explanations are super helpful

Thank you so much! 👍

The explaining style is amazing, thank you.

Thanks, that explains the whole idea of orthogonality

Best intro on this topic I've found. Part2 doesn't seem to be in the cards but thanks for this intro!

Can someone explain why, at 6:06, the electrons on the P-side arent being pushed back into the N side by the electric field. It seems like electrons are only reactive to an electric field on the N-side. Not on the P-side. This doesn't make sense to me.

Thank you sir. I really appreciate your teaching .

The video really helps a lot!! Thank you!

Where is part 3????? 😰😰😰

Is there an intuitive explanation for energy-band diagrams with multiple sub-bands? Some materials such as GaAs have different effective masses which lead to multiple overlapping E-K curves. Spin-Orbit interaction also causes band splitting. I'd love an explanation on this!

Very clear explanation of the E-k band diagram.

kT is the thermal energy. the ratio (E-Ef)/kT defines the ratio between electronic kinetic energy and thermal energy (random atom vibration). So if (E-E`F)/kT >> 1 than the free electrons have more knietic energy than the random motion of the atoms in the lattice. If (E-E`F)/kT << 1 than the free electrons have less knietic energy than the random motion of the atoms in the lattice. For (E-E`F>0 than there will be free electrons, that could be in the conduction band. For E-Ef<0 than the electrons are bounded to the atoms/molecular orbid.

pretty helpful! thanks

This much of clearity is a new experience in itself. Oh god how lucky his students are. Teachers generally rush away these topics which are complex in the end with printed definition and no explanation. Thanks

Really helpful for we engineers. ✌🏻

Vt is the minimum voltage at the gate to invert.

you are god. thx

incredible video

0:36 You got rid of all my anxiety 😆

thanks a lot!

朝闻道😊

Pl send part2 it is nice video

Why is E and H used as opposed to D and H or E and B.
