10 Ιουν 2024 · Holes: These are the absence of an electron in the valence band, effectively acting as positively charged carriers. When an electron leaves its position in the valence band, it leaves behind a hole that can move as neighboring electrons jump to fill it.
What is a hole in a semiconductor? Example? A gap in the valence band where an electron should be. Ex. by adding an element like boron with only 3 valence electrons to the semiconductor silicon, there is a hole where the fourth electron of boron should be.
