In a semi-conductor, electrons in the n-type part are repelled from the
positive particles in the same band. Electrons from the p-type band move
up to replace the 'holes' caused by the previous electrons, therefore
causing a current. Why are the electrons repelled from the positive
particles in the n-type, when they should be attracted to them??
