Thank you. This is fantastic. I really helps me to see what is happening in real time in every part of the diode.

You have made a nice video though I could sense some hesitation in some places like when you speak about how the forward bias affects the barrier (which you got right but can be stated more accurately). I suggest you refer to the books in the references below. What is a pn junction ? A pn junction allows current in one direction only. It blocks current in the reverse direction. When a pn junction is formed, a potential barrier designated Vo comes into existence and is typically around 0.6 to 0.7 volts for silicon junctions. When the barrier whose Vo is 0.7 volts is disturbed by applying a forward bias of say, 0.6 volts, the current increases and the increase becomes steep for small increments of the forward bias value a little greater than 0.68 volts. Large currents are observed when the forward bias is 0.69 volts which is closer to the barrier voltage of 0.7 volts. The forward bias can never exceed the potential barrier voltage nor can it bring the barrier down to zero volts. That is the reason you seldom see current vs volt graphs of pn junction diodes beyond a volt or so. How does the bias remain less than the barrier in an operational diode? The voltage bias applied drops in the bulk neutral regions of the diode. The current in a forward bias adjusts to fulfill the conservation of current law and the rate of recombination. A detailed description of the pn junction with a distinct approach using surface charges, alignment of Fermi levels, creation of the barrier, the distinct processes of diffusion, drift, recombination and the influence of the electric field on the energies of electrons is provided in the following textbooks. Electrostatics and circuits belong to one science and not two, that of electricity and magnetism. To know how they are unified visit this link matterandinteractions.org/articles-talks/ and view the article 'A unified treatment of electrostatics and circuits. B. Sherwood and R.

so a diode allows current to pass through when activated Like a gate. so why wouldnt use a mosfat instead because a mosfat also allows current to go through when activated.
