Abstract: The effect of the indirect exchange of particles adsorbed on a graphene nanoribbon on the width of the induced energy gap and the effective mass of carriers is studied. Analytical dependences of these characteristics on the concentration of adparticles, the adsorbate–substrate binding energy, and the energy level of the adsorbed particle are obtained.

Keywords: graphene nanoribbon with zigzag edges, indirect interaction of adparticles, energy gap, effective mass.
