The electron transport through a short period modulated two-dimensional electron system exhibits clear negative differential conductance (NDC). The modulation parameters place the NDC peak clearly into the validity range of miniband conduction and it is therefore attributed to Bloch oscillations of electrons in the lowest miniband. In contrast to conventional superlattices the NDC in our device ...
