Abstract
We study the collective electronic excitations and the corresponding electron energy-loss spectrum of a single graphite layer, such as one finds floating on Ni(111) and Ru(001) graphitic surfaces. The spectrum is compared to that of three-dimensional (3D) graphite; similarities and differences are pointed out. Direct comparison of our single layer results with Electron Energy Loss Spectroscopy (EELS) data on Ni(111) is very favorable, and demonstrates how in this geometry an extra peak of purely kinematic origin may arise when w = q·v.
