Fine structure of excitons in InAs quantum dots on GaAs(110) planar layers and nanowire facets
Pierre Corfdir, Ryan B. Lewis, Lutz Geelhaar +1
We investigate the optical properties of InAs quantum dots grown by molecular beam epitaxy on GaAs(110) using Bi as a surfactant. The quantum dots are synthesized on planar GaAs(11…
Modelling the electronic properties of GaAs polytype nanostructures: impact of strain on the conduction band character
Oliver Marquardt, Manfred Ramsteiner, Pierre Corfdir +2
We study the electronic properties of GaAs nanowires composed of both the zincblende and wurtzite modifications using a ten-band k.p model. In the wurtzite phase, two energetically…
Self-assembly of InAs nanostructures on the sidewalls of GaAs nanowires directed by a Bi surfactant
Ryan B. Lewis, Pierre Corfdir, Jesús Herranz +4
Surface energies play a dominant role in the self-assembly of three dimensional (3D) nanostructures. In this letter, we show that using surfactants to modify surface energies can p…
Quantum dot self-assembly driven by a surfactant-induced morphological instability
Ryan B. Lewis, Pierre Corfdir, Hong Li +4
In strained heteroepitaxy, two-dimensional (2D) layers can exhibit a critical thickness at which three-dimensional (3D) islands self-assemble, relieving misfit strain at the cost o…
