Multilayer structures of InGaAs/GaAs quantum dots fabricated by submonolayer migrationstimulated epitaxy have been studied experimentally by scanning tunneling microscopy and results are presented. These results clearly show that in multilayer structures, ordering of nanoobjects into rows occurs in InAs and InGaAs heteroepitaxial layers.
