Abstract

Intrasubband plasmons in modulation doped multi-quantum well structures are investigated by low temperature micro Raman spectroscopy. The in-plane plasmon dispersion is measured up to about 7×10⁵cm^-1, which is four times the range acessable in earlier experiments. The results agree well with the predictions for an infinite 2DEG superlattice. A new resonance enhancement between the E₀ and E₀+Δ₀ quantum well energy gaps is observed.
