A little about me: I'm a fourth-year Ph.D. candidate in the EECS department at UC Berkeley working on nanofabrication, electromagnetics, and electronics. I have a wonderful cat named Maxwell (because Schrodinger was just too much), and spend much of my free time hiking and camping.

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)?

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.

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

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

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wrBsqiE0vG4.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.

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.
@gekinmepan
@gekinmepan Месяц назад
Electrons moving towards the junction in the P-type region leave behind holes which counteract their negative charge. Similarly, holes moving towards the junction in the N-type region leave behind electrons.

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.
@Galileosays

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.

Hello, very informative video thanks. How did you define the coded function's coefficints? I missed it, maybe the most important part. 😅 Thanks.
@hopefullysoonaweldingengineer
@hopefullysoonaweldingengineer 2 месяца назад
I got it. you simply put the coded T and W values in terms of uncoded themselves into the function and that's it.
