On the dispersion relation of plasmons in a gapless-graphene-based superlattice with alternating Fermi velocity
P. V. Ratnikov Prokhorov General Physics Institute, Russian Academy of Sciences, Moscow, Russia
Abstract:
A graphene-based superlattice formed owing to the periodic modulation of the Fermi velocity is considered. Such a modulation is possible in graphene deposited on a strip substrate of materials with significantly different static dielectric constants. The dispersion relation for plasmons has been derived for this system in the case where the Fermi level lies in the low miniband. The problem of absorption of modulated external electromagnetic radiation because of the excitation of plasmons has been discussed.
