Lithographyically defined, room temperature low threshold subwavelength red-emitting hybrid plasmonic lasers
Ning Liu, Agnieszka Gocalinska, John Justice +9
Hybrid plasmonic lasers provide deep subwavelength optical confinement, strongly enhanced light-matter interaction and together with nanoscale footprint promise new applications in…
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…
Unexpected aspects of strain relaxation and compensation in InGaAs metamorphic structures grown by MOVPE
A. Gocalinska, M. Manganaro, E. Pelucchi
We present a selection of stack designs for MOVPE grown InxGa1-xAs metamorphic buffer layers following various convex-down compositional continuous gradients of the In content, sho…
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…
