dont know why this engineering physics was in ncert class 12 but still it was really really helpful 🙏🙏🙏🙏

[@EngineeringPhysicsbySanjiv]

glad to know that..

Thank you very much.. keep watching and share with friends.. creating new videos.. surely upload in near future..

[@GaurangaBarman-i5x]

Amazing explanation of this very confusing topic Best explanation of this in the overall KZbin sir... Thanks a lot ❤❤❤❤❤ Keep uploading videos like this it will help us much to understand such topics... Thank you 😊😊😊

[@AmanKumar-my6sl]

Amazing explanation Sir. I wish could get teacher like you in my college.

[@EngineeringPhysicsbySanjiv]

SIR YOU COULD HAVE GIVEN SILICON, AN AWESOME SEMICONDUCTOR WHY DIAMOND , DIAMONDS ARE INSULATORS BUT excellent explanation sir thank you sooooo much( its coming in 12th but not engeneering)

[@EngineeringPhysicsbySanjiv]

For Silicon the same explanation applies for 3s 3p band and for Germanium for 4s 4p band. As the size of atom is more in Si and further more in Ge, the equilibrium interatomic distance is reached earlier and the energy gap reduces. Even though it is 12 std concept it is required as a prerequisite to understand the energy band diagram. So, I have included it. Nice to hear that you liked it.. Thank you..

[@DevSingh-sc9xl]

mindblowing explanation sir... Thank you

[@tvprakadeesh7914]

Sir could you list the semiconductor material which works in low temperature region s such as polar regions . And how electronics devices work in polar regions because si and ge range doest match .iam obsessed with this doubt sir

[@EngineeringPhysicsbySanjiv]

Please check the link - www.extremetemperatureelectronics.com/tutorial1.html You may get answer to your question..

[@Neeraj-is1jt]

Can u pls explain that at 7:00 after formation of single band of (8N States and 4N electrons) why we again split into two bands of 4N states?

[@parthgoel8730]

Amazing video I humbly request u to make some videos on Quantum Statistics and Quantum Mechanics Finite well and Tunnelling Effect as there is not that much of content available on youtube regarding that kindly consider it .. :) :)

[@EngineeringPhysicsbySanjiv]

Thanks.. will try

[@suchismitabehera5783]

Sir can we accomadate two electron with opposite spin in one energy level. So that quantum state is different but enegy is same. So that we called it degerancy. So my question is in one energy level two electron with opposite quantum state is available.

[@priyanshudimri5794]

[@anonymous-wc6fj]

Now i know why my teacher plotted x axis as 1/r because we can't compress them more after equilibrium distance And it's better to show 1/r as you not gonna plot it after reaching equilibrium distance value

Sir can you upload a video on E Vs K diagram differentiating conductor, semiconductor and insulator ? Because everyone has uploaded showing the semiconductor only there is no clue of conductor and insulator.

[@EngineeringPhysicsbySanjiv]

To understand this E-k diagram you need to have some understanding of quantum mechanics. Please go through kzbin.info/www/bejne/q4qzfJuIrbl2nLs which explains this E-k diagram in a simple language..

[@kumarreddy1636]

How energy gap is formed and why?

[@EngineeringPhysicsbySanjiv]

The energy bands and energy gaps are formed due to the periodic potential energy of electrons in a crystal because electrons behave like waves. so need to apply the quantum mechanical concepts in order to understand this. Yu can refer to the material on Kronig-Penney model for more understanding.

[@anandsp1179]

Amazing teaching for us

[@charlieangkor8649]

Enery of electron. Which energy? Potential? Kinetic? Total?

[@EngineeringPhysicsbySanjiv]

In an atom , the energy of the electron, will be the potential energy (which depends on the position of the electron relative to the nucleus) as well as a kinetic energy.
