@@kiransrinivasan6370 better than having heavy accent making it hard to understand for some folks. I didn't fully understand it but will keep watching it till I do. Thanks for the video.
Thanks! After watching a number of other video's that tried to explain diodes, I found this one to be the first that clearly explains how the depletion region and electric field forms and works. It helped that you explained that the N- and P-doped material is neutral (has no charge). That explains why a field is formed, and I missed that information in other videos.
You may also refer the books in this reply. 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.

4:26 you said applied voltage > forward bias voltage will make currents flow, but why is that when you said that when there is more applied voltage the diode will behave as an open switch.
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.
This video finally helped me understand how the depletion region works and why little to no current flows when the diode is reverse biased. I read about it in a book but it was hard to understand. Thanks.

we dont actually join ptype and ntype because then due to surface irregularities current wouldnt flow but rather we dope the same material.PLEASE CORRECCT ME IF I M WRONG
One of the best explanation here on YT. Many others does not understand the difference between power source polarity and electric receiving component polarity and semiconductors. The latter do not carry the electrical potential. Maybe they should study how capacitors work and think twice.
This video really saved me it's around my 20th and I finally understood it. Thanks! However, I've got a question. Why does the junction act as a barrier??
When electrons flow from N to P,and holes from P to N, after a point of time there are so many electrons in Ptype that they actually repel more electrons from coming in thus creating a barrier,similarly holes get form a positive charge in Ntype after a point of time and that repels more holes from coming in.Here the main concept is like charges repel
In the depletion layer Some electrons migrate from p - type but Y it does not moves further in n-type and y the hole created in n-type cant attract further electrons
Wondering explanation . I saw many videos explaining but this amazing. My concept is clear. I have been searching for the logical explanation of working principle of diode.
Sir can you tell about that battery positive terminal is high potential (electrons) so how can it repulse p junction in this circuit pls tell me what is happening there
had to play this video with 1.5 speed.. would have been better to reduce that goofy hand drawing same thing over and over again, however, great explanation!
Some of the othe "specialists" (who dont get a slightest idea) show the potential current inside semiconductiors flow thru the whole circuit what is WRONG. I like this tutorial. It very good.
they are vacany for electrons as in an electron which was there before has been displaced and thus a positive charge is created as always when electron leaves positive ion is created.but we dont call it positive charge but hole and a hole is a charge carrier
isn't holes the empty space on atom orbits ? why is there holes without the atom structures themself ? and how do they leave their orbits and roam freely in a solid without their orbits ?
god i'm so sick of watching hands flickering all over diagrams and not being able to read things that are behind it. this is the best video yet but i have to watch it over and over again because the voice does not pronounce words correctly.
Thank you for the feedback ila ila. We will take this on board for future videos. We will improve both the voice, and the hand movements. Have a great day.
You caught it! actually, the direction you meant is of the electrical field and since E = - grad V, the potential difference direction should be the opposite so it is correct then. But it's a brilliant catch :)
Thank you for watching!

The best on junction explanation period
Thank you for your kind words Aimilios! :)
at 3:03 their is a mistake because barrier potential is from n type to p type
4:26 you said applied voltage > forward bias voltage will make currents flow, but why is that when you said that when there is more applied voltage the diode will behave as an open switch.
we can't combine a ptype and n type semiconductor to form a pn junction diode bcz of surface irregularities.

This section is based on Solid State Physics. All of us shoul know about Semiconductors, band theory in short, Doping etc.
the background music is very disturbing.it makes the tutorial very tiresome to follow.
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.
Brilliant video S Ghosh. Animation looked like calligraphy. Which software did you use to create this video? How did you make this video?
please .... song's title ????
Good explained!Nice Sir.
This video finally helped me understand how the depletion region works and why little to no current flows when the diode is reverse biased. I read about it in a book but it was hard to understand.
Thanks.

Music sucks.... Try some electronic or no music at all
You dont need the resistor if its reverse biased there's no current ! 😂 You needed it when it was conducting !!

Some of the othe "specialists" (who dont get a slightest idea) show the potential current inside semiconductiors flow thru the whole circuit what is WRONG. I like this tutorial. It very good.
Readme .txt I think there is a mistake here. He is taking about the depletion region not the whole diode.
Yeah , great exp , but i really hate digital voice over and stupid repetitious, distracting music..
Good sir
Thank you Raju :)
Very good sir this is education.
excellent video that i had ever seen

Holes what r they
they are vacany for electrons as in an electron which was there before has been displaced and thus a positive charge is created as always when electron leaves positive ion is created.but we dont call it positive charge but hole and a hole is a charge carrier
isn't holes the empty space on atom orbits ? why is there holes without the atom structures themself ? and how do they leave their orbits and roam freely in a solid without their orbits ?
I had the exact same question in mind
this is supposed to be a dopped semi conductor
this is supposed to be a dopped semi conductor
I love it, diodes truly one of a kind ! Best regards
Thank you for your kind words Benjamin! Happy to hear you found our video useful 🙂
god i'm so sick of watching hands flickering all over diagrams and not being able to read things that are behind it. this is the best video yet but i have to watch it over and over again because the voice does not pronounce words correctly.
Ikr? the non uniform reading got into my nerves.
The voice is matching not like indian accent can't understood that

Thank you for the feedback ila ila. We will take this on board for future videos. We will improve both the voice, and the hand movements. Have a great day.
Nice video
Best explanation on diode ever!
Best explanation on youtube
Great experience with excellent
who needs music damn it
Is there any mistake about the direction of the barrier potential ? I think it must be the opposite direction, or am I wrong ?
You caught it! actually, the direction you meant is of the electrical field and since E = - grad V, the potential difference direction should be the opposite so it is correct then. But it's a brilliant catch :)
Nguyễn Duy Anh yeah you're right
You mean electric field as told by pfesd but in the video, the are showing di-pole moment -ve to +ve
FU conventional flow Theory
I think u r correct
very good
and thanks
Awsome..!
