What is Wannier–Stark level anticrossing in biperiodic superlattices about?

## Abstract The complex interplay of coherent and incoherent transmission channels in biased biperiodic superlattices is studied utilizing hot‐electron spectroscopy. It is found that coherent transport through the superlattices is dominated by the progressive localization of the Wannier–Stark states of two subminibands. This electric field dependence is lifted at special superlattice bias conditions where anticrossings between the Wannier‐Stark states of neighboring subminibands are induced. Additionally, LO‐phonon mediated transmission channels open up at electric fields where the Wannier–Stark splitting between individual states exceeds the LO‐phonon energy.
