incorrect ?Solution
In semiconductors, a hole is the absence of an electron in the valence band and acts as a positive charge carrier . When an electron gets excited to the conduction band, it leaves behind a hole. While both electrons and holes contribute to conduction, they move differently and do not have the same mobility . Electrons generally have higher mobility than holes due to their lower effective mass and freer movement in the conduction band.
