Abstract
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 d iffraction pattern and atomic force microscopy measurement confirmed t he formation of the (In,Mn)As QDs. The structure grown on GaAs (100) s howed a broad range of dot sizes with irregular shape. For the structu re 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.
