The purpose of this review is to survey the status of the theory and experiment which can
contribute to our knowledge of plasmon excitations in synthetic semiconductor …

We provide a self-contained theoretical analysis of the dynamical response of a one-
dimensional electron system, as confined in a semiconductor quantum wire, within the …

Intersubband resonances in a semiconductor quantum well (QW) display fascinating
features involving various collective excitations such as Fermi-edge singularity (FES) and …

Grating-coupler-induced collective intersubband transitions in a quasi-two-dimensional
electron system are investigated both experimentally and theoretically. Far-infrared …

The collective charge-density excitations, the intra-and intersubband plasmons, and their
manifestation in far-infrared transmission spectroscopy are studied for coupled quantum …

We investigate the collective and single-particle excitations of an electron gas, quantum
confined in a quasi-one-dimensional quantum-well wire, in the presence of a magnetic field …

In the framework of the current-response scheme we develop the theory of magneto-optical
absorption of the quasi-one-dimensional electron gas synthesized in semiconductor …

Interlevel electromagnetic response of individual spherical quantum dots (SQDs) as well as
of two-dimensional (2D) rectangular lattice of spherical quantum dots is considered …

We report on the observation by Raman scattering of one-dimensional plasmons in deep-
etched wires with lateral sizes w down to 30 nm. We determine the dispersion of these …

The effects of the potential barrier height on the collective excitations of a electron gas
confined in a GaAs-AlxGa1-xAs quantum wire of rectangular cross-section are investigated …
