We present an alternative method for the exact calculations of the Wannier-Stark (WS) localization in a long periodic potential corresponding to a (50 Γ /30 Γ ) GaAs/Ga 0.7 Al 0.3 As superlattice. We show that the electric field dependence of the electron wavefunction has unique localization dynamics.
