Stacking faults as quantum wells in nanowires: Density of states, oscillator strength and radiative efficiency
P. Corfdir, C. Hauswald, J. K. Zettler +6
We investigate the nature of excitons bound to I1 basal-plane stacking faults [(I1;X)] in GaN nanowire ensembles by continuous-wave and time-resolved photoluminescence spectroscopy…
Investigating the origin of the nonradiative decay of bound excitons in GaN nanowires
Christian Hauswald, Pierre Corfdir, Johannes K. Zettler +9
We investigate the origin of the fast recombination dynamics of bound and free excitons in GaN nanowire ensembles by temperature-dependent photoluminescence spectroscopy using both…
Exciton Footprint of Self-assembled AlGaAs Quantum Dots in Core-Shell Nanowires
Yannik Fontana, Pierre Corfdir, Barbara Van Hattem +7
Quantum-dot-in-nanowire systems constitute building blocks for advanced photonics and sensing applications. The electronic symmetry of the emitters impacts their function capabilit…
Sub-meV linewidth in GaN nanowire ensembles: absence of surface excitons due to the field-ionization of donors
Pierre Corfdir, Johannes K. Zettler, Christian Hauswald +3
We observe unusually narrow donor-bound exciton transitions (0.4 meV) in the photoluminescence spectra of GaN nanowire ensembles grown on Si(111) substrates at very high (> 850 deg…
