Figure 1.

The single-barrier transmission coefficient and the tunneling time. The single-barrier transmission coefficient 1/|α|2 (gray lines) and the tunneling time τ1 (dark lines) as functions of the reduced barrier width b/λ, when the electron energies are E=0.122516 eV, E=0.15 eV and E=0.2 eV. In the tunneling time curves, the Hartman effect is evident.
