Carrier scattering and mobility

[@a081sudhas2]

Your lectures videos are awesome , I learn all basic concepts of electronics devices .It helpful lot for my gate exam .thank you sir

[@dodgeking2293]

I am currently preparing for gate exam and there isn't much time until examination comes. If only I found this lectures before, my life could have been lot easier. Anyway the lectures are awesome and i am quite stunned by the amount of details and clarity of the concepts which is constant for every lectures. Thank you so much for making it available for free so that electronics enthusiast like us could able to learn about these concepts.

That mobility concept really highly conceptual.... awesome lecture :)

[@ravin754]

Very good explaination

[@priyankaroy9557]

Sir I am studying in class 12 Its Awesome

[@sanjayyadav-bb4fc]

Thank u so much sir ..it is very helpful for me ..ur teaching skill is awesome

[@louerleseigneur4532]

Awesome Thank you very much sir

[@shreya5132]

Awesome way of explaining..Thank you sir 😇

[@riteshmadishetty8450]

Awesome lectures sir, thanks a lot

16:41 guess the thermal velocity won't matter because in the particular approximation, we are just assuming electron is initially stationery (with its effective mass approximation) and that its velocity (rather speed) just keeps going from 0 to v every tau seconds in the direction of the applied field.. The real complicated picture is simplified just to this.. and so we are able to come up with mobility... the real piece of gem that is making all this approximation possible is probably the 'effective mass' approximation, right?

[@royalenfieldbullets]

can anyone please mention if Solid state course is available in NPTEL which have similar way of explanation. This course is top notch...awesome sir

Did u get it?

Drift is influenced by fields where it can be by itself of the semiconductor Or organic semiconductor

[@madakagnaneswari4973]

Thnq soooo much sir🤗

[@biswarupdas6651]

sir i will be highly thankful if u kindly upload the notes related to your lectures.

[@chetanshelar3680]

look on nptel website

[@freeandreliablejeeprep820]

thank you very much sir

How does the decrease in carrier concentration increase the mobility of carriers?

[@Neeraj-is1jt]

Did silicon and germanium having same majority charge carrier with same concentration (ex- electron) have same Mobility?

[@ghetiyaatriy5959]

Sir , what is reason behind constant velocity with external field?

[@KaviPriyan-qt6vc]

external field is constant

[@crovefefeomgtululuv]

Because the energy or can say momentum gained is lost while scattering in form of heat, light(photons in Led/Laser GaAs) or vibrations(Phonon)

[@MMTRINATHSOLASA]

Thnq sir

[@mytreyak]

while atoms vibrate at high temperature, humans vibrate (shiver) at low temperature 😁 (just for a laugh)

[@Neeraj-is1jt]

Why mobility saturates at high field?

[@Unknown-qg9nj]

whats the music's name which is played at the start of each video

[@sabaresand7309]

Hi sir, How holes having higher mass than electron, basically holes are not moving right, due to electrons(subatomic particle) occupies a free vacant ,it creates visualization of holes movement to us?

[@Neeraj-is1jt]

Same question.tell me if u got the answer

[@arrabalimaz622]

13:00 colliding with other electron toh?

[@rksadvancedclasses6387]

Three scattering mechanisms are present in a particular semiconductor material. If only the first scattering mechanism were present, the mobility would be u1=u1= 2000 cm^2/V-s, , if only the second mechanism were present, the mobility would be u2u2 =1500 cm^2/V-s ,, and if only the third mechanism were present, the mobility would be u3u3 =500cm^2/V-s . what is net mobility ?n
