What occurs during regular doping?

During regular doping, the introduction of impurities into a semiconductor results in the creation of mobile charge carriers, which can be either electrons or holes, depending on the type of doping. In n-type doping, for example, donor atoms provide extra electrons, leading to an increased number of mobile electrons in the conduction band. In contrast, p-type doping introduces acceptor atoms that create holes by accepting electrons from the semiconductor, which can lead to recombination processes where electrons fill these holes.

The presence of these mobile electrons and holes is fundamental to the electrical conductivity of the material and its behavior in electronic devices. As a result, the statement about the creation of mobile electrons and recombination accurately captures the outcomes of regular doping in semiconductors.
