Sure! This is another way of saying an electron from the conduction band returns to the valence band (although not strictly accurate as you picked up on, since there aren’t *really* any holes in the conduction band, just electrons and empty states).
@@JordanEdmundsEECS basically you can say either one at a time. either in terms of electrons or holes. I am confused about saying both for a single pair.
Sir you have covered the theoretical framework please do a video on problem solving from the book. Something in the style of "organic chemistry tutor" would help.
@@JordanEdmundsEECS I hear so many people say "degree Kelvin" it is understandable to make the mistake. Thanks for these videos this course is AWESOME!
Man you are a gift from god. Thankyou
Daw, thanks :)
Could you please elaborate on the statement "the hole returns to the conduction band"?

Sir,
Where does the recombination occur?
In the valence band or in the bandgab?

Robert, thanks for the suggestion, I'll make a few example videos over the next couple weeks.
Awesome I can't wait.
Sir by when would you be finished with chapter 8 at least?
Should be within the next 2-3 weeks, probably before then.
Sir, is 2*hf = Eg for the indirect thermal mechanism?
Roughly speaking, yes. The traps are usually assumed to be somewhere in the middle of the bandgap.
Is the RG centre recombination process observed in He-Ne Laser?
Based on mass conversation or thermodynamics ?
during generation the e-h pair uses thermal energy to do so right. What happens to that energy when they recombine?
A photon gets emitted! And probably re-absorbed, or emitted into the environment.
Sir, is this Semiconductors course in your PhD. or Bachelor's Degree? Are you originally from University of Queensland Australia?
Bachelor’s, I’m originally from UC Irvine in California.
But in your linked profile its written
Visiting Student Scholar

@@shubham1999 XD Because I haven't updated it in awhile. That was over the summer last year.
Love your videos! They are excellent! One minor "issue": Kelvin is not degrees Kelvin, just Kelvin.
Thanks! And yeah, I totally did not know that until like 6 months ago when it was pointed out to me, which is kinda hilarious.
