WebThe positive battery terminal attracts N-type majority carriers, electrons, away from the junction. The negative terminal attracts P-type majority carriers, holes, away from the junction. This increases the thickness of the nonconducting depletion region. There is no recombination of majority carriers; thus, no conduction. Web30 okt. 2016 · As indicated in figure, a large number of majority carriers i.e. holes will diffuse across the forward-biased p-n junction into the n-type material. The question then is whether these carriers will contribute directly to the base current IB or pass directly into the p-type material.
