...And then suddenly It came in my book, Hole current is also there in semiconductors and I know it. But there's a little thing that's confusing me. Is this hole current temporary? Yes, according to me. Isn't it? What if all the holes generated travels up to the negative potential. What after that? As they are atoms(positively charged). They can't move outside the material and go in the circuit like electrons are doing. So, what happens to those positively charged atoms at the negative potential? Do they remains there? Forever?

There's a second little doubt too, I've read about *recombination process in semiconductors*. So, when the electrons are moving towards positive potential and holes towards negative. Then do the **recombinations** occur? Do electrons go back into the holes?

*These are two doubts i'm having in the section **intrinsic semiconductors** of my book. Please clear these doubts. Thank you so much!*
