摘要：

The chemical etching behavior of Ga(Al)As and In(Ga)P(As) containing sandwich layers grown by metalorganic vapor phase epitaxy has been investigated using various etching solutions. The chemical background is described by a potential-pH diagram. Activation energies obtained were between 0.28 and 0.46 eV. The inclination angle of the etched walls is mainly 55-degrees. In both the systems, a transition from a reaction-rate limited process to a diffusion-rate-limited one is observed. In InP, a reactive intermediate with an inclination angle of 45-degrees could be trapped.
