Fock-Darwin States of Dirac Electrons in Graphene-Based Artificial Atoms
Fock-Darwin States of Dirac Electrons in Graphene-Based Artificial Atoms
We investigate the Fock-Darwin states of the massless chiral fermions confined in a graphitic parabolic quantum dot. In light of Klein tunneling, we analyze the condition for confinement of the Dirac fermions in a cylindrically symmetric potential. New features of the energy levels of the Dirac electrons as compared to …
