We have investigated the initial growth mechanism of MnAs on GaAs(0 0 1)-c(4 Â 4)a reconstructed surfaces. We found that the MnAs deposition on GaAs(0 0 1)-c(4 Â 4)a surface promotes to break the Ga-As asymmetric dimers and modulates the dimer characteristics to symmetric As-As dimer formation on th
