What is a charge carrier in semiconductors?

In semiconductors there are two types of charge carriers, it all depends on the type of conductivity, if it is hole, then holes are the carrier, there are more of them than electrons, if it is electronic, then the carriers are electrons, their concentration is higher. Moreover, both those and other carriers are present in any case, but the type is influenced by their concentration.
