Absztrakt:
An experimental method for detection of bound states around an
antidot formed from a hole in a graphene sheet is proposed by
measuring the ballistic two terminal conductances. In
particularly, we consider the effect of bound states formed by
magnetic field on the two terminal conductance and show that
one can observe Breit-Wigner like resonances in the conductance
as a function of the Fermi level close to the energies of the
bound states. In addition, we develop a new numerical method in
which the computational effort is proportional to the linear
dimensions, instead of the area of the scattering region beeing
typical for the existing numerical recursive Green's function
method.
