C (4×4) Reconstruction on Arsenic-Rich GaAs (001) Surface after Phase Transition

Abstract:

C(4×4) reconstruction on arsenic-rich GaAs(001) surface after phase transition has been investigated from the experiment and simulation. We found that the c(4×4) As-rich reconstruction structure of the GaAs (001) surface can be best depicted with the model which there are three As-As dimers without Ga-As dimers in a reconstructed unit cell, and these dimers are found to be aligned perpendicular to the As dimers on β2(2×4) surface.
