When a pure silicon crystal (giant lattice) is doped with boron atoms one of the four covalent bonds made between one boron atom and four surrounding silicon atoms is missing an electron as boron has three valence electrons. Is there a technical name for these holes (lack of electron in a covalent bond).
Is it acceptable to say that these holes are indirectly the charge carriers as they are allowing the movement of the electrons?
Furthermore, could you say that these holes are positively charged?(Hence the name p-type semi-conductor?).
