@ckneeha6611 3 года назад

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?

@Rohitprime0 4 года назад

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

@rizwanasindhi6633 7 лет назад

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 5 лет назад

Yeahhhh same doubt

@ravipratihast 7 лет назад

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.

@korukondamehervihari7025 7 лет назад

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 7 лет назад

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

@prateek0369 5 лет назад

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 5 лет назад

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.

@syedahamed7334 4 года назад

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...

@ckneeha6611 3 года назад

Same doubt

@Abhijeet114 2 года назад

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

@giseleazanga6923 3 года назад

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 4 месяца назад

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
