Figure 6From: Anisotropic Confinement, Electronic Coupling and Strain Induced Effects Detected by Valence-Band Anisotropy in Self-Assembled Quantum DotsOne layer AFM 1 × 1 μm image of In 0.4 Ga 0.6 As QDs in samples grown under different conditions. Sample A (left) shows 1D chain-like ordering along the [ 0 1 ¯ 1 ] direction. Sample B (right) shows mostly isotropic or randomized dot distribution in the (001) plane.Back to article page
