Figure 4From: Formation of Ga droplets on patterned GaAs (100) by molecular beam epitaxy3-D top-view atomic force microscope (AFM) images . 3-D top-view atomic force microscope (AFM) images show the surface morphologies of Ga metal droplets on GaAs (100) with 20, 10, and 5-ML depositions at the Tsub of 400°C. AFM images are 2(x) × 2(y) μm2, and scale bars correspond to the heights of the images.Back to article page
