1.A hole is the absence of an electron in a particular place in an atom.Electrons and holes do not move as rapidly through the solid materials as electrons do in a vaccum.The holes move more slowly than the electrons.The holes and electrons move in opposite direction. 2.Here if the electric current moving from left to right ,than the holes will be moving in opposite direction that is from right to left. Regardless of the semiconductor type ,with the potencial applied there will be net effect.Both electrons and holes contribute to total current flow,altough they are moving in opposite directions,they are of opposite charge.
