Barrier Potential

[@aviakg]

your channel may not have a large number of viewers right now not but i am sure that in future your channel will be favorite among electronics students. thank you .

[@pradeepgodavarthi8313]

its already my fav channel ...i learnt digital electronics here itself ;) got A grade in my university xam

[@alterguy4327]

Already an Electronic hotspot

[@giseleazanga6923]

I learnt circuit analysis here and had A grade

[@kalyanitewari]

aww :_)

[@kajalgoswami6251]

your guess was correct . now this channel is our prime source to study

Very informative. Concept clearing teacher.. Thankyou sir

[@larryzhang3446]

Many thanks to this channel. I learn analog eletronics and hope to expand my career scope.

[@EliyasAbdulaziz-ii7lh]

Im so grateful to get such an interesting tutorials.

[@scholar7879]

😂 So it was so easy and my lecturar was blowing our heads in class.. Thanks man,that's very educative.

[@ingowenzel6818]

hello and have many thanks for your excellent explanations which is unparalleled in comparison to other electronics tutorials.........

[@mostafatarekadam8861]

God save the king!! Thank you so much sir, may the lord save you ❤️❤️

[@batman6432]

Sir i m really thankful to you for making me understand depletion region... Which i really never could undertand. My teacher never gave that. Seriously eduction system in India, as i m from india, shoul be changed .

[@ShambhaviTripathi]

WOnderful lectures. Sir, please complete the analog electronics series. It is very helpful

[@elizabethakinyi3843]

[@rizwanasindhi6633]

i m bit confused about the potential barrier curve . why it is so that it is zero in p region and then linearly increases when depletion width starts and then remain constant in n region . please please answer it . because this will solve my problem of read diode characteristics

[@venkataapparao2699]

Yeahhhh same doubt

[@rohitvlogs9374]

you explain everything good .. sir vry good work

[@abmuqeet08]

what is the effect of concentration of impurity on barrier voltage?

[@korukondamehervihari7025]

if an immobile ion having electron is combining with hole and forming a positive immobile ion,why again those positive immobile ions on n-side are represented along with electrons(plus sign in a circle with minus sign in its power)?

[@hadiaamin1466]

korukonda meher vihari only the immobile ions of the depletion layer combine with holes, others are prevented from combining with holes because of the barrier potential

[@adityagarg6734]

isnt it that P side should have majority as holes 0:38

[@divjotsingh7514]

sir,awesome ur work is

[@ravipratihast]

sir, in this lecture at last part you did explain a numerical in which I am facing a simple problem i.e barrier potential you are getting, is 0.757(VALUE OF SILICON) but when I followed the step above of your it comes 0.329 (VALUE OF GERMENIUM)...PLEASE HELP ME IN IT.

[@vanshtomar6527]

Got the solution..? After 5 yrs

[@chandrimadas8691]

whoever got the wrong ans of last question are using log, instead of log use ln,you will get correct one@@vanshtomar6527

[@baL88537]

​@@vanshtomar6527💀😭

[@Rohitprime0]

But sir by mass action law n(e).n(p)=n(i)^2.,so it will be always ln(1) ,which mean build in potential will be always zero

[@tk.4062]

Not when it is doped.

[@ckneeha6611]

Sir u said silicon barrier potential is 0.7 at only room temperature because they given in question But we get 0.7 only at Na=10^15 and Nb=10^16 so if we change their concentration at room temperature then we get different barrier potential right?

when i try divide this value 10^13/2.25 appear another value it's not same in video ?can any body help me

have u noticed about ln ?????

i understood, thanks sir

According to barrier potential, which one is a good semiconductor Ge or Si?

Is there another formula for calculating Vbi interms of depletion region?

[@saminakhalil2470]

In theraja 's book the calculation of potential barrier is quite different he is using a formula Vb = detltaV+0.7 . And I don't know what to do . Is there any one who can help me out ? :(

[@prateek0369]

Sir i have a doubt.... I cannot understand how the formation of immobile ion in depletion region and the initially immobile ions present at the p-side or n-side are takes place?

[@aswin__r]

Consider p side of on junction diode. When we add dopant like boron which has 2 8 3 electronic configuration, the valence she'll has 3 electrons. When doped due to an absence of 1 electron they receive an extra electron from Si lattice thus turning into a stable -ve ion and creating hole in the Si lattice.

[@AliAli-yn1ks]

please is there any different between Barrier pottential and pottential Barrier ? thank you very much

[@tiruveediveeraraghavulu4447]

How to use 1.5*10^10 Please tell me answer sir

[@giseleazanga6923]

Please I’ve a question Why are the ions in the p type semiconductor negative? Where as the impurity atom used is boron and its negatively charged

[@parthanayak1620]

Boron has 3 electron in outer shell but for bonding it should have 4 electrons in outer shell. So it needs one more electron. Since it is going to accept one electron so it becomes negatively charge

[@Abhijeet114]

According to Mass action law ni^2=ne×nh ,so built in potential is always 0.please clear NA,ND,Ne,Nh properly.

[@surajittripathy1583]

Can you tell me please weather the calculation for this barrier potential is important for my bsc 2nd year course??

wrong calculation of log at the end

[@tejalbarnwal7617]

Why will the graph for potential vary linearly from p side to n side?

[@syedahamed7334]

Why do say that the barrier potential of si is always 0.75? The ans 0.75 is because of the conc of Na Nd nd ni right? It may not br thr samr in all cases then y do take 0.75 as the barrier potential...sir plz correct me i am confused...
