Biexciton Initialization by Two-Photon Excitation in Site-Controlled Quantum Dots: the Complexity of the Antibinding State Case
Gediminas Juska, Iman Ranjbar Jahromi, Francesco Mattana +3
In this work, we present a biexciton state population in (111)B oriented site-controlled InGaAs quantum dots (QDs) by resonant two photon excitation. We show that the excited state…
Self-ordered nanostructures on patterned substrates: Experiment and theory of metalorganic vapor-phase epitaxy of V-groove quantum wires and pyramidal quantum dots
Emanuele Pelucchi, Stefano T. Moroni, Valeria Dimastrodonato +1
The formation of nanostructures during metalorganic vapor-phase epitaxy on patterned (001)/(111)B GaAs substrates is reviewed. The focus of this review is on the seminal experiment…
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…
Single pairs of time-bin entangled photons
Marijn A. M. Versteegh, Michael E. Reimer, Aafke A. van den Berg +5
Time-bin entangled photons are ideal for long-distance quantum communication via optical fibers. Here we present a source where, even at high creation rates, each excitation pulse…
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…
