Abstract :
We have grown GaMnAs films using As/sub 2/ as a function of growth temperature and Mn flux. At high Mn fluxes or high growth temperatures, a three-dimensional (3D) growth mode is observed by reflection high-energy electron diffraction. At lower Mn fluxes or reduced growth temperature a two-dimensional (2D) growth mode is observed.
