Nettet1. feb. 2024 · 0. Shortest answer: in reality, conduction by holes is just movement by all the electrons in the band, causing the hole to move, and causing net / overall conduction in the material. In a conductor / conduction band, the electrons are already able to move almost-freely, so we don't need to think about the hole concept. Nettet28. aug. 2016 · Holes are a term given to absence of electrons. The holes do not move by themselves. But, yes, holes appear to be moving in the opposite direction to electrons, when the electrons in the semiconductor device move from one vacancy to the another. Hence, here you can say the direction of the current is the direction of the holes!
