KrasovskiiarXiv preprint·2024·10.3389/fphy.2021.654845·arXiv:2412.18561AbstractBound states and scattering resonances in the unoccupied continuum of a two-dimensional crystal are considered within an exactly solvable model. A close connection of the observed resonances with those arising in Fano theory is revealed. The resonance occurs when lateral scattering couples the layer-perpendicular incident electron wave to a strictly bound state. The coupling strength determines the location of the pole in the scattering amplitude in the complex energy plane, leading to a characteristic Fano lineshape of electron transmissivity through the crystal. The timing of the resonance scattering is discussed. The analytical results are illustrated by ab initio calculations for a graphene monolayer.Read more
