(Color online) Calculated band diagram for a structure with a channel.
(Color online) Calculated dispersion curves for InGaSb (see text).
(Color online) High-resolution x-ray diffraction scans near the (004) reflection for structures with channels and varying channel composition.
(Color online) Mobility vs for channels: (a) and (b) . The room-temperature sheet density for the InGaSb samples was .
(Color online) Mobility vs sheet density for quantum wells. The well thicknesses (in nm) are indicated for the normal structures. The well thickness was fixed at for the inverted structures. The line is a guide to the eye for normal structures with channels.
