摘要：

A serpentine superlattice quantum-wire array avoids the tilt sensitivity of a tilted superlattice and promises significant 1D confinement at the 10 nm scale. Transmission electron micrographs confirm the intended geometry. Three independent polarization measurements, an energy shift, and the light-hole-heavy-hole splitting at 1.4 K, when compared with theory, demonstrate 1D valence band states and 2D conduction band states. All five measurements are explained by lateral AlxGa1-xAs wells land barriers of x = 0.12 and 0.21, respectively, thus characterizing the step-flow growth.
