Abstract
Semiconductors are fabricated in
many ways such as molecular beam
epitaxy and others. Making two
layers of GaAs and AlXGa1-XAs
on top of the other that create
deference in the energy gaps because
AlXGa1-XAs have greater Eg than GaAs.
That cause the electrons to fail
from AlGaAs to the plane between the
two layers and goes in many circular
trajectories correspond to the
magnetic modulation.
The essential point in computational
physics is not the use of machines,
but the orderly application of
numerical techniques in place of,
and in addition to, analytical
methods, in order to make accessible
to computation as large a part of
physical reality as possible. |
