One of the clearest ones I have seen and I have watched about ten different ones. The others probably helped too though haha. I recommend watching several because you may pick up a slice of the puzzle you didn't realize before. For me in this one, it was realizing that those atoms with an extra donor electron (or vice versa for other side) actually become positive-ish since the electron is floating around mobile????
5.56 but how is it possible that electrons move from cathode to anode, but the flow of current is to the opposite direction? i thought that the flow of electrons determines the flow of current
WOW so far this animation and explanation is THE BEST one on youtube. Do you have a paypal? or patron? I would like to donate to you for your excellent work.
Why does one electron move from a silicon atom in the lattice to an adjacent boron atom rather than just stay with the silicon atom after doping with boron to form the P region of the diode?
But more electrons in the N type creates more negative charge, you have them as positively charged and vice versa with the P type. Can you please explain the switch please
Really very good video helping to understand ! Just one small correction if you don't mind . As you very well pointed out Diode comes from the Greek word di (δύο - dyo) meaning two and the other part is odos (οδός - odos ) meaning road - street or way depending the usage . Thank you again for this great video
The free electrons of the n-type fill the holes in the p-type material creating full valence shells for those atom. This prevents the passing of more electrons from the n-type material. because electrons only have so much energy to move from valence shell to valence shell. Check out about 2:48 that may answer better.
In a diode (made with 2 semi-conductors, P and N), there is a depletion zone created as soon as the N and P are in contact each other without being connected to a battery. Can we say that in a transistor (PNP or NPN), there is too a depletion zone between each NP junction, so we would have P-depletion-N-depletion-P and N-depletion-P-depletion-N ?
i see more than 20 video on youtube . they all just explain working of diode. and did not explain the difference between ions and electrons.. but this video clear my concept about how diode work.. one thing more still did not understand what is a hole? as electron as a physical substance.. but hole is empty space so why they call positive charge?
Thank You @Adil. Since in an atom the negative charge of the electrons is balanced by the positive charge of the atomic nuclei, the absence of an electron leaves a net positive charge at the hole's location
This is the conventional way combined with half real way of moving particles inside. Would be better to have 2 kind of explanations the conventional and the real one.
