Abstract
The dielectric function of a spherical two-dimensional electron gas (2DEG) is calculated in the framework of the random phase approximation. The whole spectrum of electron-hole and plasmon excitations is then calculated numerically, along with the electron energy loss function. The dispersion and strength of the plasmon mode as functions of the angular momenta are also obtained. The results are compared with those of a planar 2DEG with the same areal density.
