Did you know?
WebbA single pentavalent atom (impurity) in a silicon crystal can take the place of one of the tetravalent Si atoms in the crystal structure. Four of its five valence electrons will participate in covalent bonds with its four Si neighbors, and the remaining electron is weakly bound by the resultant positive ion.
