    Man you are a gift from god. Thankyou

    Could you please elaborate on the statement "the hole returns to the conduction band"?

    • @JordanEdmundsEECS
      @JordanEdmundsEECS  5 ปีที่แล้ว +5

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

    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.

      Robert, thanks for the suggestion, I'll make a few example videos over the next couple weeks.

    Sir by when would you be finished with chapter 8 at least?

    • @JordanEdmundsEECS
      @JordanEdmundsEECS  6 ปีที่แล้ว

      Should be within the next 2-3 weeks, probably before then.

    Sir, is 2*hf = Eg for the indirect thermal mechanism?

    • @JordanEdmundsEECS
      @JordanEdmundsEECS  5 ปีที่แล้ว +1

      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?

    • @JordanEdmundsEECS

      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.

    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.
