Towards quantum dot arrays of entangled photon emitters
Gediminas Juska, Valeria Dimastrodonato, Lorenzo O. Mereni +2
We show that with a new family of pyramidal site-controlled InGaAsN quantum dots it is possible to obtain areas containing as much as 15% of polarization-entangled photon emitters…
Semiconductor nanostructures engineering: Pyramidal quantum dots
E. Pelucchi, V. Dimastrodonato, L. O. Mereni +2
Pyramidal quantum dots (QDs) grown in inverted recesses have demonstrated over the years an extraordinary uniformity, high spectral purity and strong design versatility. We discuss…
Physical properties of highly uniform InGaAs pyramidal quantum dots with GaAs barriers: Fine structure splitting in pre-patterned substrates
L. O. Mereni, V. Dimastrodonatoa, G. Juskaa +2
InGaAs Quantum Dots embedded in GaAs barriers, grown in inverted tetrahedral recesses of 7 μm edge, have showed interesting characteristics in terms of uniformity and spectral narr…
A novel site-controlled quantum dot system with high uniformity and narrow excitonic emission
L. O. Mereni, V. Dimastrodonato, R. J. Young +1
We report on the optical properties of a newly developed site-controlled InGaAs Dots in GaAs barriers grown in pre-patterned pyramidal recesses by metalorganic vapour phase epitaxy…
A site-controlled quantum dot system offering both high uniformity and spectral purity
L. O. Mereni, V. Dimastrodonato, R. J. Young +1
In this paper we report on the optical properties of site controlled InGaAs dots with GaAs barriers grown in pyramidal recesses by metalorganic vapour phase epitaxy. The inhomogene…
