A1 - Steffens, Oliver A1 - Rössler, Ulrich T1 - Observability of the acoustic plasma mode in double-layered quantum dots JF - Physica E: Low-dimensional Systems and Nanostructures N2 - Double-layered quantum dots represent a novel realization of a multi-component plasma system. By modelling the system and applying classical concepts we investigate the oscillator strength of the acoustic plasma mode and its dependence on the system parameters. In view of recent experimental results, we discuss the observability of this collective excitation.
