Super explanation.....I'm very clear in this concept after watching this....thanks....

Well explained 👏👌now I understood this topic🤩🤩🤩

EZ and concise explanation... thank you!

Is there a possible either electrons or holes jumped out of the C. B Or V. B

Well explained, Thanks for sharing!

Well explained, thank you.

It's use ful to me great job sir

super explained sir. thank you so much

Explains the semiconductor with the help of E-K diagram and equilibrium distribution of electrons and holes.

It's very easy to understand thank u

Supper explanation,thank you bro

honestly ... good explanation thanq

Give detailed explanation with equations

Sir please mera doubt clear kijiye hmko ye nhi smjh aa rha ki zero kelvin temperature pe electron kaise jump kr skta hai and hole kaise create ho skta hai sir please bataiye sir please

Well explained 😊

The guy is right. The Fermi energy is only defined at absolute zero, while the Fermi level is defined for any temperature. en.wikipedia.org/wiki/Fermi_energy

Aur sir yeh bhi bataiye ki fermi level ka existance zero kelvin temperature pe kaise ho skta hai kyuki sir zero kelvin temperature pe toh electron only valence band mein rhega wo jump khaan kr paayega sir please bataiye hm bahut problem mein hai

Agr semiconductor main Fermi level Conduction band ko touch kr je ya cross kr je CB ko to Kia Ho ga

Excellent sir

Plg give a hole video of moderne phy

Very nice explanation

So nice thanks sir

HI. I was wondering how to calculate fermi level for conductors where band gaps are overlapping. Kindly suggest... Thanks...

AHHA, here it is I searched literally tonnes of sources for this

if no electron occupies any level in the band gap, how come the fermi level sits in there while it means the probability of 50% to be occupied by an electron. if it's a band gap then it has a 0% probability of being occupied by an electron, what am I missing?

Like a substance can have a centre of mass at a place where there's no mass (like a ring has centre of mass at its centre)

Why the electrons are more than holes then the fermi level will moves to conduction band. Please explain clarity in another video.

since electrons already appear loosely connect to the main atom. they can easily get to conduction band

Numeral bhi solve kijiye sir

How do we prove that 2Ef=Eg

@sunriseryadaav7493

Take Ne=Nh,then substitute the values of them...later take natural log on both sides ....after that take me=mh...,then log1 becomes zero...so ef=eg/2...

Sir conduction band me eletron hi hote he Kya . Holes nahi hote Kya

I think only electrons exist in conduction band.

In which conductivity is more-intrinsic or p-type semi conductor ?

@anant8934

p type

@roshnirs1378

Extrinsic ie p and n type :)

tank you sir

Why does the Fermi band move towards the conduction band when the number of electrons is greater than that of holes? If it moves upwards, won't the probability of finding an electron increase? So how can we say that Fermi level is where the probability is 50-50?

You already explained the postiion of Fermi level in intrinsic semiconductor and again why are you drawing E(if )in extrinsic semiconductor

thanks!!!

thanks

Sir ak question Hy

Thank you very much!!

thankyou sir

Thank you 😊😊

Could anyone explain - I thought that electrons could only be either in the conduction band or in the valance band, not in the band gap. So how can electrons be at the fermi level half way between? Confused!

Only at t=o.as the temp increaseor decrease there is change in fermi level

As the temperature increases, the bonds start to break making hole-electron pairs. This way, there's two posible scenarios: If it was an excentric material, the proportion of majority charge porters start to decrease, and might reach a point where it's insignificant. If it was an intrinsic, the proportion stays the same, half electrons and half holes. So you can see that at any temperature, in an intrinsic material, the fermi level stays in the same state of energy, and in an intrinsic, it starts to behave like an intrinsic as the temperature increases

At absolute zero temperature bro not at any temperature
