@article{Belouad2019EnergyLO, title={Energy levels of graphene magnetic circular quantum dot}, author={Abdelhadi Belouad and Bouchaib Lemaalem and Ahmed Jellal and H. Bahlouli}, journal={arXiv: Mesoscale and Nanoscale Physics}, year={2019} }

We study the energy levels of graphene magnetic circular quantum dot surrounded by an infinite graphene sheet in the presence of an electrostatic potential. We solve Dirac equation to derive the solutions of energy spectrum associated with different regions composing our system. Using the continuum model and applying boundary conditions at the interface, we obtain analytical results for the energy levels. The dependence of the energy levels on the quantum dot radius, magnetic field and…
