Abstract The dispersion of sheet plasmons in two-dimensional electron gas (2DEG) systems prepared on Si(1 1 1)-( 3 × 3 )-Ag surface was investigated by angle-resolved high-resolution electron-energy-loss spectroscopy (HREELS) in an in-situ ultrahigh vacuum environment. The evolution of dispersion at the low coverage of additional silver adatoms shows a behavior associating with two-dimensional adatom gas phase and the critical coverage to sustain this phase is also determined. Dispersion at… CONTINUE READING
