The plasmon density of states (DOS)p(ω) of a layered electron gas (LEG) is studied theoretically. It is shown that p(ω) is a linear function of frequency ω as ω goes to 0, and then increases more rapidly as ω tends to the screened, three dimensional plasma frequency ωp. We also study the partial densities of state for constant K and qz, where K and qz are the magnitude of the transverse and perpendicular momentum transfers. A possible experimental probe for the plasmon DOS is discussed. © 1993 Springer-Verlag.
