Diffusion of Ga adatoms at the surface of GaAs(001) c(4x4) $\alpha$ and $\beta$ reconstructions

Marcin Mińkowski, Magdalena A. Załuska-Kotur

Diffusion of Ga adatom at the As rich, low temperature c(4$\times$4) reconstructions of GaAs(001) surface is analyzed. We use known energy landscape for the motion of Ga adatom at…
