Carrier Drift Current: Mobility

[@yousefhannouneh]

i recently started a similar course in my uni and I've always been amazed by the subject and you made it x10 better and I'm now just binge watching this playlist

[@suruchiverma48]

This video series is super helpful and you're very clear. Thank you v much!

[@rabiacaglayan]

You are the greatest. Thanks a lot :)

my hero thanks for the series

[@JordanEdmundsEECS]

You are welcome :)

Sorry i'm a biologist that starting to pick up physics, I was wondering how do we get the value of the effective hole/ e mass and the q (elementary charge). Is it provided by the fabrication facility as well by the material i use or i can count it. Very grateful to watch your video, you helped me to understand a lot of the physics concepts in my PhD work. Appreciate.

I was once a biologist trying to pick up physics too (one of my degrees is Biology). The effective mass is usually gives in tables for a given semiconductor (for example for Silicon, Germanium, ITO, and so on), and q is a fundamental constant that never changes equal to roughly 1.6*10^-19 Coulombs.

@@JordanEdmundsEECS Dr., do u think you can make a video on diffusive , ballistic and hopping transport?

[@SomeshRajvlogs]

Thanks Sir Again 🙏🏼😌

Hey, at 10:20 shouldn't v_n be v_p if we denote holes with p and electrons with n? Thanks for the vid!

[@omartusson]

that is not v_n , it's v_h which is velocity of the hole. so Velocity of hole = mobility of hole * Electrical field.

Why when electrons collide with protons they scatter? Since they are opposite charges, they won't become a single neutron?

[@suruchiverma48]

Can you mathematically tell me how to get the first probability equation? Intuitively I get it, but mathematically how is it equal to dt divided by lifetime?

[@sauravti]

You videos are awesome 👏👏👍

[@MohammedIslamElshiekhElsmani]

Interesting!!

[@mahmoudbiomy8281]

thanks

[@suruchiverma48]

And finally the mobility of holes should be the total mobility using ion and lattice scattering right? So instead of (mu)p it's actually (mu)p total?

[@JordanEdmundsEECS]

Yup!

better graphs than most of CSU professor's pathetic graphs, some of then you can even understand what they write. or what they are saying cuz their super heavy accents. it sucks!! and i am paying for it :)
