摘要
Boron-doped p-type diamond has at least three activation energies. The first one is 0.30 similar to0.35 eV, which is the energy from the ground states of boron to the valence band. The second one is 0.05 similar to0.07 eV, which is the energy from the impurity band to the valence band which becomes observable when the impurity concentration increases. The third one is 0.003 eV or less, which is the energy of the variable range hopping.
