ABSTRACT
Chapter 1 deals with steady-state chiral tunneling. We have
concluded that the transmission probability is ideal (T = 1) if the momentum of an incident electron is directed perpendicular
to the chiral barrier, which constitutes the Klein paradox. Another
interesting moment is that an incident electron is converted into
a hole inside the chiral barrier. However, if the angle of incidence
is finite, the elementary excitation represents a combination of the
electron and the hole which propagate over two different A and B
sublattices.
