Bound states in the continuum: Localization of Dirac-like fermions
Europhysics Letters, 2014•iopscience.iop.org
We report on the formation of bound states in the continuum for Dirac-like fermions in
structures composed by a trilayer graphene flake connected to nanoribbon leads. The
existence of this kind of localized states can be proved by combining local density of states
and electronic conductance calculations. By applying a gate voltage, the bound states
couple to the continuum, yielding a maximum in the electronic transmission. This feature can
be exploited to identify bound states in the continuum in graphene-based structures.

Abstract
We report on the formation of bound states in the continuum for Dirac-like fermions in structures composed by a trilayer graphene flake connected to nanoribbon leads. The existence of this kind of localized states can be proved by combining local density of states and electronic conductance calculations. By applying a gate voltage, the bound states couple to the continuum, yielding a maximum in the electronic transmission. This feature can be exploited to identify bound states in the continuum in graphene-based structures.
