Abstract

Very dilute two-dimensional hole systems were probed by resonant inelastic light scattering. This extremely high mobility system occurs in Al _xGa _1-xAs/GaAs quantum wells designed specifically for their light insensitivity. We find that the depolarization shift in intersubband transitions decreases linearly for hole densities below p=6.6 × 10 ¹⁰ cm ^-2, dropping to zero below p=1 × 10 ¹⁰ cm ^-2.
