    • Note
    • The MQW structure was (from the top of the structure, with layer thicknesses in nanometers): 5.0; 85× (35.0 - / 4.0 - / 20.0 - /35.0); 35.0 -; 300. Here, the barrier layers (underlined) are Al0.15 Ga0.85 As and the wells are GaAs. Doped layers are in bold; the top and bottom contact were silicon-doped at 2× 1018 cm-3, while the modulation doping in the 4 nm Al0.15 Ga0.85 As region was 1× 1018 cm-3.

    • Note
    • The lifetime of the heavily doped contacts was found to be weakly frequency dependent, reducing by a factor of two across our spectral range. This frequency dependence was included in the data presented here, and will be discussed in a future publication.
