- A mesoscopic system is a solid small enough in size,
so that the interference of electron wave-functions can be observed. A typical
size of a mesoscopic system is around
which is larger than
the microscopic size of around Å and smaller than the
macroscopic size which is more than

Note that this is unique for the contact between a metal and a CNT.
In a conventional, planar semiconductor device the position of the FERMI
energy is pinned by metal-induced gap states .

- Screening is defined by
the inverse dielectric function. An external potential induces a charge density in
the system. This induced charge density gives rise to a change in the potential
via the COULOMB interaction, which in turn yields an induced charge density and
so forth. The result of this infinite series of charge redistribution process
is the screening of the external potential.
