The stability of the electron gas in jellium against the formation of charge-density waves is studied using the density-functional formalism. Charge-density waves occur in three-dimensional jellium for rₛ>26 and in two dimensions for rₛ>17 in our approximation. The theory is applied to two-dimensional electron gases on liquid-helium surfaces and in semiconductors.
