Collective electronic excitations within the subband structure of semiconductors with doping superlattices are discussed. We find that heterodoping superlattices with a layered electron-hole system are good candidates for the observation of acoustic plasmons. Using the self-consistently calculated subband structure we investigate collective electron intersubband transitions and their coupling to LO phonons.
