Abstract
Resonant inelastic light scattering is used to probe plasmon excitatio ns in shallow etched GaAs/AlGaAs quantum wires. A semitransparent Scho ttky gate on top of the structure allows a strong variation of the car rier density in the system. The wavevector dispersion of the collectiv e excitation spectrum is studied from the regime of confined wires to a charge density modulated system.
