Anomalous Stranski-Krastanov growth of (111)-oriented quantum dots with tunable wetting layer thickness

Driven by tensile strain, GaAs quantum dots (QDs) self-assemble on In(0.52)Al(0.48)As(111)A surfaces lattice-matched to InP substrates. In this study, we show that the tensile-strained self-assembly process for these GaAs(111)A QDs unexpectedly deviates from the well-known Stranski-Krastanov (SK) gr...
