The importance of overcoming MOVPE surface evolution instabilities for >1.3 m metamorphic lasers on GaAs
Enrica E. Mura, Agnieszka M. Gocalinska, Megan O'Brien +7
We investigated and demonstrated a 1.3 m-band laser grown by metalorganic vapour phase epitaxy (MOVPE) on a specially engineered metamorphic parabolic graded InGaAs…
Micro-transfer printing high-efficiency GaAs photovoltaic cells onto silicon for wireless power applications
Ian Mathews, David Quinn, John Justice +5
Here we report the development of high-efficiency microscale GaAs laser power converters, and their successful transfer printing onto silicon substrates, presenting a unique, high…
Vanishing biexciton binding energy from stacked, MOVPE grown, site-controlled pyramidal quantum dots for twin photon generation
Stefano T. Moroni, Simone Varo, Gediminas Juska +3
We characterized stacked double-pyramidal quantum dots which showed biexciton binding energies close to zero by means of photoluminescence and cross-correlation measurements. It wa…
Three-dimensional Self-assembled Columnar Arrays of AlInP Quantum Wires for Polarized Micron-sized Amber Light Emitting Diodes
Andrea Pescaglini, Agnieszka Gocalinska, Silviu Bogusevschi +7
A three-dimensional ordered and self-organized semiconductor system emitting highly-polarized light in the yellow-orange visible range (580-650 nm) is presented, comprising self-as…
Statistical study of stacked/coupled site-controlled pyramidal quantum dots and their excitonic properties
S. T. Moroni, T. H. Chung, G. Juska +2
We report on stacked multiple quantum dots (QDs) formed inside inverted pyramidal recesses, which allow for the precise positioning of the QDs themselves. Specifically we fabricate…
Engineering of selective carrier injection in patterned arrays of single-quantum-dot entangled photon light-emitting diodes
T-H. Chung, G. Juska, S. T. Moroni +3
Scalability and foundry compatibility (as for example in conventional silicon based integrated computer processors) in developing quantum technologies are exceptional challenges fa…
