Complex optical signatures from quantum dot nanostructures and behavior in inverted pyramidal recesses
Complex optical signatures from quantum dot nanostructures and behavior in inverted pyramidal recesses
A study of previously overlooked structural and optical properties of InGaAs heterostructures grown on (111)$B$ oriented GaAs substrates patterned with inverted 7.5-\ensuremath{\mu}m pitch pyramidal recesses is presented. First, the composition of the confinement barrier material (GaAs in this work) and its growth temperature are shown as some of the key …
