Abstract

Two-dimensional (2D) plasmons in the monolayer graphite formed on TiC(111) surface have been detected by using electron energy loss spectroscopy. The plasmon due to the intraband transition has shown a peculir dispersion proportional to a sqare root of the wave vector parallel to the surface in the energy region of 0 - 3 eV. In addition, the other branch appearing at high energies above 5.4 eV presumably originates from the longitudinal 2D plasmon due to the interband transition.
