Coupled intra- and intersubband plasmon-phonons beyond the random-phase approximation in double heterostructures

The spectrum of the collective excitations of a double heterostructure, coupled intra- and intersubband plasmon-phonons is analyzed including exchange and correlation effects. Exchange and correlation effects are considered within the local-density-approximation of the time-dependent density functio...

Description
Summary:The spectrum of the collective excitations of a double heterostructure, coupled intra- and intersubband plasmon-phonons is analyzed including exchange and correlation effects. Exchange and correlation effects are considered within the local-density-approximation of the time-dependent density functional theory. It is shown that the effect of exchange and correlation is more pronounced for the intersubband modes than for the intrasubband modes.
