Fermi level and Fermi Dirac distribution function

[@chikaokolo4929]

You are one of the best physics teachers on KZbin. I looked everywhere for a simple explanation, and this is the first time Fermi levels make sense.

5:07 By the grap Probability of occupation decrease below fermi energy level and Probability of occupation decrease(not increase)above fermi energy level

[@rajeswarinunna105]

Compared to 0 K probability increased as temperature increased

Sir I have one doubt if you clear then I m very great ful to you sir.sir if temprature increases then Fermi level may not be the top most filled energy level some level above filled with electron and some level below empty.so in the graph Fermi function vs energy looses it's step character .my question is Fermi function tends to zero or totally zero if temp increases

[@EngineeringPhysicsbySanjiv]

If the temperature increases to infinitely high value, then according to the relation, Fermi function will tend to half.

[@suchismitabehera5783]

@@EngineeringPhysicsbySanjiv sir if not infinite but above room temprature I want to share graph,through whatsapp possible

[@EngineeringPhysicsbySanjiv]

@@suchismitabehera5783 For moderate temperature, the graphs are already shown in the video. For energy levels, much below, fermi function will be 1, near fermi level, it will reduce, at fermi level it will be half, just above feermi level it will be greater than zero and much above fermi level it will be zero.

Sir again after 3 year i have also a interview and i want to give a demo regarding fermi level. Sir in starting if i say that in a conductor conduction band is parially filled and valence band is completely filled and electrons are distributed in diff energy level according to paulis exclusion principles i m right or not.

[@EngineeringPhysicsbySanjiv]

In conductor conduction band and valence band are not separate.. you can say they overlap.. and gap is zero

[@suchismitabehera5783]

Yes sir thank you. I'm forgetting to say this.sir my interview is on dt 27.12.2023 sir blessed me.

[@nileshyadav9881]

Sir occupation index linear function hai ya step ya exponential?

[@EngineeringPhysicsbySanjiv]

At small temperature it can be approximated to be a linear function. At higher temperatures, it is no longer linear..

[@shubhrajit2117]

Thanks a lot :)

[@williamcolgate5708]

I think its just 'Kelvin' and not 'Degree Kelvin'

Ya.. degree Kelvin was old way

What us E in fermi dirac function

[@suchismitabehera5783]

Sir this the defination of fermi level for conductor only. Am i right. For semiconductor this defination of fermi level changed.

Yes.. see next video for semiconductor
