A 1 cm 3 specimen of a metal or semiconductor has the order of 10 22 atoms. In a metal, every atom donates at least one free electron for conduction, thus 1 cm 3 of metal contains on the order of 10 22 free electrons, [28] whereas a 1 cm 3 sample of pure germanium at 20 °C contains about 4.2 × 10 22 atoms, but only 2.5 × 10 13 free electrons and 2.5 × 10 13 holes.
e2 ⋅ eV −1 ⋅ μm −1. Vacuum permittivity, commonly denoted ε0 (pronounced "epsilon nought" or "epsilon zero"), is the value of the absolute dielectric permittivity of classical vacuum. It may also be referred to as the permittivity of free space, the electric constant, or the distributed capacitance of the vacuum.
