    Very, Very well done.(Wish you could pre-write the words to lessen my anxiety level.) I think that there will Always be heat generation, even in recombination, albeit sooo tiny.
    And a pn junction is not a diode (and vice-versa) it only contains it as do transistors, scr, jfets, ect...
    Enough of my criticism. Do leds use a specific substrate instead of silicon?

      You know electrons try to occupy lowest energy possible.

    • @siddharths4846

      LED is heavily doped semiconductor. So there is excess of minority charge carreirs, so they recombine more often than normal diodes

    What happen if all electron recombine with holes.

  • @susmithatalupula9791

    If recombination takes place in forward bias why do its depletion region decrease instead of increses

    • @hkkapoor5703
      @hkkapoor5703 3 года назад

      Hii
      As I read , when ele. and holes recombine
      at that time a EHP generate in p side and ele move towards +ve terminal (p side)
      and hole move (fulfill near by electron ) towards -ve terminal and such more and more charge carriers generates in forward bias .
