We have grown (In,Mn)As quantum dots (QDs) on GaAs (100), (211)B and (311)B substrates. The observation of reflection high energy electron diffraction pattern and atomic force microscopy measurement confirmed the formation of the (In,Mn)As QDs. The structure grown on GaAs (100) showed a broad range of dot sizes with irregular shape. For the structure grown on GaAs (311)B, (In,Mn)As QDs with bimodal size distribution were observed. The (In,Mn)As QDs grown on GaAs (211)B showed improved size uniformity compared to those grown on GaAs (100) and (311)B. The effect of Mn as a surfactant on InAs nanostructures was also studied.
