Abstract
A natural superlattice (NSL) in silicon carbide polytypes is shown to introduce a
miniband structure into the conduction band, which leads to a number of effects in phenomena of
quantum-mechanical transport and impact ionization when the electric field directed along an axis
of NSL (axis C in crystal). These processes are absolutely traditional when the electric field is
perpendicularly to this axis. The parallel field phenomena are explained by the effects of the
Wannier–Stark localization (WSL) among them the Bloch oscillations effect is most prominent
today.
