Issues related to the usage of nitrogen as carrier gas for the MOVPE growth of GaSb/InAs heterostructures on InAs pseudosubstrates
Hanno Kroencke, Agnieszka Gocalinska, Valeria Dimastrodonato +2
GaSb/InAs/GaSb layer stacks have been grown on InAs metamorphic substrates (pseudosubstrates) by MOVPE, using nitrogen as major carrier gas. We demonstrate that GaSb growth by nitr…
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…
Evaluation of defect density by top-view large scale AFM on metamorphic structures grown by MOVPE
Agnieszka Gocalinska, Marina Manganaro, Valeria Dimastrodonato +1
We demonstrate an atomic force microscopy based method for estimation of defect density by identification of threading dislocations on a non-flat surface resulting from metamorphic…
Conditions for entangled photon emission from (111)B site-controlled Pyramidal quantum dots
G. Juska, E. Murray, V. Dimastrodonato +4
A study of highly symmetric site-controlled Pyramidal In0.25Ga0.75As quantum dots (QDs) is presented. It is discussed that polarization-entangled photons can be also obtained from…
