▎ 摘  要

We propose an experimentally friendly scheme for trapping quasi-relativistic electrons in graphene by an electromagnetic beam with circular polarization and a spatially inhomogeneous profile with an intensity dip. The trapping is achieved due to the effect of band-gap opening outside the trapping region. The proposed mechanism allows for non-invasive electron confinement in graphene without any need for the chemical patterning of the sample or the application of metallic gates.
