Figure 2From: Various Quantum- and Nano-Structures by III–V Droplet Epitaxy on GaAs Substrates2D and 3D atomic force microscope (AFM) images of InAs QDs on GaAs (100) surface at various fabrication temperatures: a 20, b 25, c 30, and d 35°C. Depending on the growth temperature, the size and density of QDs vary. The 2D AFM images are 1000 (x) × 700 (y) nm2 and the 3D, insets are 250 × 250 nm2Back to article page
