Abstract

Using the time-dependent local-density approximation, we investigate low-dimensional plasmons (PL’s) in a metallic strip monolayer on a semiconductor surface. We find a series of PL dispersion branches where the node number in oscillation of the induced electron density δn across the strip increases one by one with rising energy. The 0-node and 1-node modes are edge PL’s with different parity in the δn distribution. In each PL branch with a larger node number, character of area PL starts to appear with an increase in wave number q. In a broad q region, we examine the energy-loss intensity, the energy dispersion, and the δn distribution in each mode. Our analysis shows how dramatically the δn distribution of the PL mode evolves with change in q, and how the character of the δn distribution is correlated with the energy-loss intensity.
