Electronic excitations of the multilayered graphite

Electronic excitations of the multilayered graphite are studied within the random-phase approximation. The loss function, which characterizes the intrinsic excitation spectrum, is derived in details. The interlayer atomic hopping integrals and the interlayer e-e Coulomb interactions are taken into account simultaneously. They could create new plasmon modes and e-h excitation channels.
