Abstract
The formation of GaAs pyramidal structures on nanopatterned GaAs substrates and the evolution of associated equilibrium crystal shapes (ECS) are systematically studied and simulated. Three distinct types of ECS are observed with high-resolution scanning electron microscopy (HRSEM), and they are defined by three crystal plane families including {11n}, {10n}, and (001). The controlled formation of these GaAs ECS is achieved through their growths in patterns of different opening diameters and under growth conditions of varying growth times and growth rates. Simulation results of the dynamic ECS model based on Wulff’s theory not only strongly resemble the GaAs pyramidal structures in the HRSEM images but also successfully demonstrate the evolution progress of the ECS formation.
