Indium segregation during III-V quantum wire and quantum dot formation on patterned substrates
Stefano T. Moroni, Valeria Dimastrodonato, Tung-Hsun Chung +4
We report a model for metalorganic vapor-phase epitaxy on non-planar substrates, specifically V-grooves and pyramidal recesses, which we apply to the growth of InGaAs nanostructure…

Complex optical signatures from quantum dot nanostructures and behavior in inverted pyramidal recesses
G. Juska, V. Dimastrodonato, L. O. Mereni +6
A study of previously overlooked structural and optical properties of InGaAs heterostructures grown on (111)B oriented GaAs substrates patterned with inverted 7.5 um pitch pyramida…
