Thanks sir now we are learning from your KZbin channel Becuase in our collage not study well just time waste to going to college for class we just go for attendance and study from your channel 🤩 thank you sir ❤️🥳🤩

Sir, What is the significance of negative effective mass? Plz reply

[@gautamvarde]

In the context of electrons in semiconductor materials, negative effective mass occurs when the curvature of the energy bands in the material is such that the effective mass of an electron is negative at certain points in the band structure. This typically happens near points where the energy dispersion relation (the relationship between energy and momentum) has an inverted curvature. Thank you dear

Sir UV vis and DLTS na video kyare banavso

[@T1s_kashyap]

Sir my College professor taught us a different derivation which is about three pages long and the conclusion is m*= h^2/(d^2E/dK^2) too much different but I saw your video and it is very easy to understand so what should I do the one which my professor taught me or the one you. actually I have my semester exam so if you can answer please reply.

[@gautamvarde]

It depends on weightage of marks dear

[@T1s_kashyap]

@@gautamvarde I'm doing your's then atleast it's easy and makes sense 😄.

[@RaviNagar16]

@@T1s_kashyap Its easy to derive and memories but it doesnt make sense. How did became m1a ? Why does m and m1 differs ? Its not answered in this video.

[@T1s_kashyap]

@@RaviNagar16 i didn't get what you are saying but best of luck finding answer

[@Indiangamerz823]

Sir , we can write this in gtu exam , book me dusra equation derived kiya h , plz reply sir ?

[@gautamvarde]

Definitely dear

[@_PND]

Sir effective mass ka use kaha hota hai ? Hme kya fayda effective mass find krke ?

[@gautamvarde]

The effective mass is used in transport calculations, such as transport of electrons under the influence of fields or carrier gradients, but it also is used to calculate the carrier density and density of states in semiconductors. Thanks dear

[@sneharajaparmarparmar]

Sir vacuum spelling

[@Kishan_Narrator]

why we have to take m & m1 , why electrons have different mass ? mass can neither be created nor destroy atom can neither created nor destroy

[@gautamvarde]

According to Einstein's theory of relativity, if object is in motion then it's mass changes. That concept all ready we studied in 12th science. Thank you dear

Sir equation of effective mass Wala topic rah gya????

[@gautamvarde]

Equation of effective mass has never been asked. If it will be asked in exam then you can write about Effective mass of Electron. As in both topics m star (Effective mass of electron) valu is derived. So don't worry. You may get full marks. Thank you dear.
