Figure 3From: Various Quantum- and Nano-Structures by III–V Droplet Epitaxy on GaAs Substrates2D and 3D AFM images of ring-shaped InGaAs nanostructures on GaAs (100) by droplet epitaxy: a 250, b 355, and c 450°C. Large 2D AFMs images are 20 (x) × 16 (y) μm2 and the 3D insets are 600 × 600 nm2. The dotted-circle emphasizes the location of nanostructuresBack to article page
