Do the holes actually moves hall effect?

Answer 1

Picture a little line of chairs with people sitting in them except the first chair. Now the person in the second chair moves to the first chair. The second chair is empty. Visualize each person in turn moving to the empty chair. The empty chair is now at the other end of the line. This is similar to the way electrons and holes appear in semiconductors. The electrons move and create holes. The holes only appear to move, but the effect is the same. Do the holes move? Effectively, yes, but only by virtue of electron movement.
