Abstract:Our study investigated the emergence of spatial Quasi-Bound States (QBSs) in graphene mono- layers induced by rectangular potential barriers. By solving the time-independent Dirac equation and using the transfer matrix formalism, we calculated the resonance energies and identify the QBSs based on probability density functions (PDF). We analyzed two types of structures: single and dou- ble barriers, and we find that the QBSs are located within the barrier region, at energies higher than the single barrier. Addi… Show more
