The hole current is due to the movement of valence electrons from one covalent bond to another. Why is then the name hole current?

Expert Answer:
The basic reason for the current flow is the presence of holes in the covalent bonds. Therefore, it is more appropriate to consider the current as due to the movement of holes.
